Steps to reproduce:
---
- Install `website_sale`.
- Create a product and from the Sales tab, add alternative products, making sure all products are published on the website.
- Open the main product on the website.
- In the alternative products section, open the editor, click the `brush` icon under `card design`.
- Under Actions > Buttons, click on the `cart` icon.
- Save the changes and click the `Add to Cart` button on an alternative product.

Issue:
---
- Clicking the `Add to Cart` button on alternative products does nothing.

Root cause:
---
- At [1], the `AddToCart` interaction uses the selector `.oe_website_sale button[name="add_to_cart"]` to find and attach click handlers. When the dynamic snippet renders alternative products, `startInteractions` is called on the `.dynamic_snippet_template` div. It searches for the button inside that div, but at [2], no element wrapping the button has the `oe_website_sale` class in the rendered product card template. So the selector matches nothing, and no click handler is attached.

Fix:
---
- Add `oe_website_sale` to the `o_wsale_product_btn` wrapper div in the product card template so the button becomes a descendant of `.oe_website_sale` within the injected content, allowing the interaction to attach correctly.

Steps to Reproduce:

* Create a Hungarian company on 19.0 (or earlier).
* Configure NAV credentials through Settings.
* Upgrade the database to saas~19.2.

Issue:

* The upgrade fails while reloading the Hungarian chart template.

```

Cause:

* Since the introduction of the Hungarian tax migration using `account.chart.template.try_loading('hu', company)` in saas~19.1, upgrades reload the Hungarian chart template.
* When `l10n_hu_edi` is installed, chart template loading triggers `_l10n_hu_edi_configure_company()`, which performs NAV credential validation through `_l10n_hu_edi_test_credentials()`.
* The credential validation performs a live request to the NAV service, making the upgrade dependent on an external service. https://github.com/odoo/odoo/blob/saas-19.2/addons/l10n_hu_edi/models/res_company.py#L99-L109 https://github.com/odoo/odoo/blob/saas-19.2/addons/l10n_hu_edi/models/template_hu.py#L11

Fix:

* Bypass NAV credential validation during the migration.
* The migration only updates localization data and does not modify the configured EDI credentials.
* This prevents temporary NAV connectivity issues from aborting the upgrade process.

### Issue before this commit:
When reversing an invoice in a Peruvian company, the "Cancel Reason" entered in the credit note window is not propagated to the Peruvian EDI tab of the resulting Credit Note. Only the Credit Reason is successfully reported.

### Steps to reproduce the issue:
1. Download Accounting and l10n_pe
2. Switch to PE company
3. Create an invoice and confirm it
4. Create a credit note for the invoice with a cancel reason and a credit reason and click the reverse button
5. See that in the Peruvian EDI tab only the Credit Reason is reported but not the Cancel Reason

### Cause of the issue:
In the l10n_pe_edi module, the override of the _prepare_default_reversal method maps the l10n_pe_edi_refund_reason to the new move's values, but completely omits the mapping of the wizard's textual reason field to the l10n_pe_edi_cancel_reason field of the resulting credit note.

### Reason to introduce the fix:
To ensure the generated credit notes contain all required information for the Peruvian EDI (SUNAT). Mapping the cancel reason guarantees that the electronic document accurately reflects both the refund code and the descriptive cancellation text provided by the user.

Steps to reproduce
---
1. Register a grouped customer payment over several invoices, leaving one of them only partially paid.
2. Register a second grouped payment over two invoices: the partially paid one and a brand new invoice.
3. Open the first payment, its "Reconciled Invoices" smart button now lists the new invoice from the second payment, which it never paid.

Issue
---
The smart button is built from the stored `invoice_ids` many2many, which shares its relation table with `account.move.matched_payment_ids`. After reconciling, the register wizard links the payment to its invoices with `lines.move_id.matched_payment_ids += payment` at https://github.com/odoo/odoo/blob/f726393267a28cedd5febd2106de17ae3838f3ff/addons/account/wizard/account_payment_register.py#L1212.

When the payment groups several invoices, `lines.move_id` is a multi-record recordset. Reading `matched_payment_ids` on it returns the union of the payments already linked to all those invoices, and `+=` writes that union back to every invoice as a `(6, 0, ...)` replace command. So an invoice already paid by an earlier payment spreads that earlier payment onto every other invoice grouped in the new one, including brand new invoices, which then wrongly appear on the earlier payment.

### Issue:
In DATEV customer and supplier exports, partners outside the European Union still had the `EU-Land` and `EU-UStID` fields filled

However, these fields must only be used for EU countries

For non-EU countries, the `Land` field should be filled instead, and is required whenever the country is not Germany https://developer.datev.de/en/file-format/details/datev-format/format-description/debitorskreditors

### Cause:
`_l10n_de_datev_get_partner_list` did not distinguish between EU and non-EU countries

As a result, any partner with a VAT number could populate `EU-Land` and `EU-UStID`, even if the country was outside the EU

Greece also requires a special case: its VAT prefix is `EL` so the `EU-Land` too, while the country code used in `Land` must remain `GR`

### Steps to reproduce:
- Install `l10n_de_reports` and switch to the DE company
- Create a customer in Switzerland with a valid VAT number
- Create and confirm an invoice for that customer
- Go to Accounting → Audit Reports → General Ledger
- Select the full year
- From the gear menu, export DATEV DATA (zip)
- Open the `EXTF_customer_accounts` file

### Before the fix:
`EU-Land` and `EU-UStID` are filled for the Swiss customer, while `Land` is empty

### After the fix:
`EU-Land` and `EU-UStID` are empty for non-EU countries such as Switzerland, while `Land` is correctly filled

`Land` is filled using the following priority:
1. Partner country_code
2. Country extracted from the VAT number
3. Empty

### Issue
Since the introduction of the Tax Returns feature in 18.3, it was no longer possible to generate a Closing Entry as the button has been replaced by Returns
The Return mechanism implies that you need a Return Type in order to make a Closing Entry using the Validate button

Additionally, using the Generic Tax Report by default creates a risk in Multi-VAT environments, as it mixes taxes from all countries instead of isolating Peruvian taxes

### Cause
The new 18.3 accounting workflow requires at least one active Return Type associated with a country-specific report variant to display the Return options and process the closing entry Peru was relying on the Generic Tax Report, without a dedicated report variant
No Return Type was configured, which blocked Odoo's automatic VAT closing workflow and prevented the system from prompting the user to configure the required closing accounts

### Steps to reproduce
- Install `l10n_pe_reports` and `accountant`
- Switch to a PE Company
- Go to the Tax Report

Before the fix, no Returns button is available for any of the existing reports, making it impossible to use Odoo's automatic process to configure the tax accounts and trigger the closing entry

### Notes
This is fixed by creating a dedicated Peruvian tax report variant directly in Enterprise that inherits from the generic tax report A custom handler is added to force the domain filtering on Peruvian taxes only, and a corresponding Return Type is defined to restore the full closing entry process safely

## Issue
When scheduling a sign request, the request appears immediately on the portal for the requested signer.

## Steps to reproduce
1. Install *Sign* (`sign`)
2. Create and send a sign request
    - Signer 1: Any portal user (e.g., Joel Willis)
    - Use the clock icon to schedule the signature request to a future date
3. Log in as the portal user used in step 2
4. Navigate to Signature Requests
5. **The signature request already appears in the list, even though it was scheduled for a future date.**

## Cause
The portal filters the sign requests shown based on the `is_mail_sent` field, which does not properly reflect when the signature request is shared to the user.

https://github.com/odoo/enterprise/blob/9898272f17809decf6c5bb4600aca46f9ffae6f0/sign/controllers/portal.py#L40

In fact, when scheduling a signature request, the `is_mail_sent` field is unconditionally set to `True`, even if the signature request will only be sent later.

https://github.com/odoo/enterprise/blob/9898272f17809decf6c5bb4600aca46f9ffae6f0/sign/models/sign_request_item.py#L289

## Fix
Since the `"scheduled"` `sign_request_item.state` option introduced by https://github.com/odoo/enterprise/commit/ed8d5a653e01b1378f0020e2f7a7c2d39fadf3e9 in 19.1, we can easily filter out the sign request items that are scheduled. That state is automatically updated by the `_cron_update_state`, introduced by the same commit as the `"scheduled"` option.

### **Steps to reproduce:**
- Install Payroll and Attendance apps.
- Create an employee with a flexible working schedule and work entry source as attendance.
- Create an attendance record for this employee.
- Create and compute a payslip for this employee.

### **Observed Behavior:**
 Worked Day lines are not generated, and Basic Wage is calculated as 0.

### **Expected Behavior:**
Worked Day lines should be populated based on attendance records.

### **Root Cause:**
During payslip computation, [_compute_worked_days_line_ids](https://github.com/odoo/enterprise/blob/4339010eb1e1633a67573d08e032f3922b0bec49/hr_payroll/models/hr_payslip.py#L1846) only generated work entries for versions having a `resource_calendar_id`  at [1]. As a result, fully flexible employees without a working schedule were excluded from work entry generation, preventing worked day lines from being computed.

[1]- https://github.com/odoo/enterprise/blob/4339010eb1e1633a67573d08e032f3922b0bec49/hr_payroll/models/hr_payslip.py#L1890-L1898

### **Fix:**
Remove the `resource_calendar_id` filter when calling `generate_work_entries` in `_compute_worked_days_line_ids` so work entries are also generated for fully flexible employees using attendance-based work entries.

**Issue**
Printing a credit note for a returned dropshipped tracked product could display the wrong lot/serial number on the invoice report.

**Steps to reproduce**
- Activate "Display Lots & Serial Numbers on Invoices"
- Create a product tracked by serial/lot and enable the dropship route
- Create two lots: "lot1" and "lot2"
- Create and confirm a SO for quantity 2
- Confirm the PO and validate the dropship for both lots
- Create and post an invoice
- Return "lot2" from the dropship picking
- Create and post a credit note for quantity 1
- Click on print -> The generated PDF displays "lot1" instead of "lot2"

**Cause**
While rendering `account.report_invoice_with_payments`, the report calls `_get_invoiced_lot_values` to determine which lot/serial numbers should be displayed:
https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L31-L32 `invoiced_qties = 1` since the credit is on a quantity of 1 https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L44 Three stock move lines are retrieved from the SO:
- the two original dropship deliveries,
- the return move for `lot2`. https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L63 However, none of them are considered as `is_stock_return` because the dropship locations use `supplier` instead of `internal`: https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L72-L76 As a consequence:
- The two original delivery move lines each keep quantity `1`: https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L69 they never pass through the return handling logic: https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L77-L80 which would make it as -1 (since `qties_per_lot[sml.lot_id]` is 0 for the first iteration of `sml.lot_id`). Thus, it does not pass by this code (since quantity is greater than 0): https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L87-L90 which would make it as 0.
- for the last one, `is_stock_return = False` as it should be, thus the quantity is 1 as it should be. The quantities are therefore accumulated as:
https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L92

resulting in:
`qties_per_lot = {lot1: 1, lot2: 2}`
instead of:
`qties_per_lot = {lot1: 0, lot2: 1}`

The report then selects the first matching lot and stops: https://github.com/odoo/odoo/blob/786c373d5ac8afdfb79eb7a7d69c5eb83b919625/addons/sale_stock/models/account_move.py#L94-L99

Cause:
----------------------------------------
Commit 121806b57816d0fbd48b5538d2a8beae35905d99 added a test verifying that the duration in German is correctly recognized. In the test, "2 Std. 30 Min. 45 Sek.", was supposed to be recognized as 2.5125 hours. But on some browser versions it fails, as in the latest Chrome version.

This is because we use `DurationFormat()` to get the localized units. This method is supported by all browsers and will use the browser's data to get the translations. This data comes from [Unicode CLDR](https://cldr.unicode.org/) which is updated regularly.

We would need to change the test depending on the Chrome version, so we just delete it. It appears that for German hours the CLDR definitions have historically shifted between two distinct representations: "Std." and "h"

As an example:
- CLDR 47:
https://github.com/unicode-org/cldr-json/blob/16f6b8578ba5fe98959034706f337674f816fc3f/cldr-json/cldr-units-full/main/de/units.json#L3526-L3527

- CLDR 48:
https://github.com/unicode-org/cldr-json/blame/4d06be52b51bb2f75688d0abe55c52a66afed790/cldr-json/cldr-units-full/main/de/units.json#L3916-L3917


So the test fails in CLDR 48 but succeeds in CLDR 47.

As the latest version of `ICU` (used by browsers) updates its dependency to CLDR 48 ([src](https://unicode-org.github.io/icu/download/78.html)) this explains why the latest Chrome version makes the test fail.

Steps to Reproduce
---
1. Open the Planning module
2. Create an open shift with allocated_hours
3. Click Auto Plan
4. Click Undo on the auto-plan notification

Issue
---
Undoing an auto-plan operation triggers recomputation of allocated_hours,
causing the shift to lose its original workload value.

Current Behaviour
---
When resource_id is set to False during undo:
- _compute_allocated_hours is triggered (depends on resource_id)
- _compute_allocated_percentage is triggered (depends on allocated_hours)
- Both fields are recalculated, potentially changing allocated_hours
  from its pre-assignment value

Expected Behaviour
---
Undoing auto-plan should preserve allocated_hours at its pre-assignment
value while allowing allocated_percentage to adapt to the new context
(open slot vs assigned resource).

Fix
---
Use protecting context manager in action_rollback_auto_plan_ids
to prevent allocated_hours from being recomputed when resource_id is
removed. This allows allocated_percentage to recalculate naturally based
on slot duration while keeping allocated_hours stable.

Scenario:

- set up turnstile
- with recent safari mac os or ios (reproduced from 26.2) go to
  /web/login page in a private window
- enter login and password and pass the turnstile challenge
- click on Log in

Result: nothing happens and there is an error in the console "An invalid
form control with name='' is not focusable."

Cause:

By default Safari has the Settings > Advanced > "Use advanced tracking
and fingerprinting protection" set to "in Private Browsing".

If this options is enabled in private browser or in all browsing, you
can't login to Odoo with turnstile because safari is preventing the
update of the element that is preventing to send the form:

<input style="display: none;" class="turnstile_captcha_valid" required>

When turnstile challenge succeeds, a value should be set to this input
that will unlock the form, the .value property is updated but the
browser Shadow Content is not (and if we remove display:none, the input
is empty).

Fix:

I've not been able to reproduce the issue without turnstile using same
situation and iframe. We don't know Safari heuristic but the unlocking
is working if:

- we use setProperty instead of .value
- we unset required
- we remove the input
- we display the turnstile_captcha_valid input before challenge

This fix replaces setting .value by setProperty, and add a failsafe of
unsetting required.

The scheduler commits after each mail batch, which is fine from cron but problematic during an import: since [29460b723f49](https://github.com/odoo/odoo/commit/29460b723f49) [`load`](https://github.com/odoo/odoo/blob/b2f3270271f6/odoo/orm/models.py#L884) uses a single savepoint for the whole run, and any commit underneath releases it, so the next `ROLLBACK TO` / `RELEASE SAVEPOINT` raises `InvalidSavepointSpecification`.

When `import_file` is in context, trigger the cron like the async path already does so the mails are queued instead of running inline.

Steps to reproduce:

0. Have Contacts and Events installed
1. Events > Events, create a published event
2. Open the event, Attendees tab > Favorites > Import records
3. Upload a file with new attendees (Name, Email, no external id)
4. Click Import

=> "savepoint ... does not exist", import fails

## The Problem
When computing a future leave balance, `_get_future_leaves_on` triggers
`_process_accrual_plans`, which iterates period by period and calls
`_get_leaves_taken` at each step. `_get_leaves_taken` re-enters
`_get_consumed_leaves` with `ignore_future=True`, but other accrual
allocations on the same employee were not guarded by `precomputed_allocations`,
causing `_get_future_leaves_on` to fire again for each of them, launching
another full accrual run recursively. With N periods and K allocations,
total work grew as $O(N^K)$.

## The Solution
Adding `not ignore_future` to the guard prevents future projection in any
nested context where it is both semantically incorrect and the source of
the blowup.

---

## Benchmarks
*Tested on a customer database with an employee having 2 accrual allocations and
pending future leave requests 6 months out:*

| | Queries | Request Time | Improvement |
| :--- | :--- | :--- | :--- |
| **Before** | 220K | 145.0s | — |
| **After** | 2.7K | 2.8s | **-98%** |

**Note:** More optimizations could be done to reduce the queries to a constant. However given the current design, it would be a bit big change and the current performance is already acceptable.

Issue:
When the sales price is changed from the product variant form for a product without configured variants, the price is updated only on `product.product.lst_price`. The main product form, opened from Inventory > Products, displays `product.template.list_price`, which remains unchanged. The same issue is visible from Purchase Orders because the product internal link on a purchase order line opens `product.product`, while the product page opens `product.template`.

Steps to reproduce:
- Create or open a product without configured variants
- Open product variant form from the internal link in a purchase order
- Change the Sales Price on the product from there
- Open the product from Inventory > Products (`product.template`)
- The template Sales Price still shows the old value

Cause:
Since version 19.1, `product.product.lst_price` is an editable stored field, allowing variant-level prices to differ from the template price. This is correct for products with multiple variants, where each variant may have its own sales price. However, for products with only one variant (the product itself), no synchronization was performed from `product.product.lst_price` back to `product.template.list_price`, leaving both product forms inconsistent.

Solution:
- Add `_inverse_product_lst_price` on `product.product.lst_price` so that When `lst_price` is written and the template has exactly one variant, set `list_price` to `lst_price` (delegates to the template)

I confirm I have signed the CLA and read the PR guidelines at www.odoo.com/submit-pr

Steps to reproduce:
- Create a storable product “P1” with Lot tracking
- Enable routes: MTO + Manufacture
- Create a BoM for the product:
    - Component: C1
- Configure the warehouse with 3-step manufacturing
- Have on-hand stock in WH/Stock with Lot 001
- Confirm a Sales Order for the product
- Confirm the generated Manufacturing Order and produce Lot 002
- In the "Store Finished Products" transfer, change the destination location from WH/Stock to WH/Stock/Shelf 1 and validate
- Check the Delivery Order reservation

Problem:
The move is reserved with Lot 001 instead of 002

When using a 3-step manufacturing flow (MTO + Manufacture), if the user manually changes the destination of the "Store Finished Products" transfer to a sublocation of WH/Stock (e.g. WH/Stock/Shelf 1), the MTO link between the production and the delivery order was incorrectly broken, causing the delivery to reserve existing stock instead of the freshly produced lot.

Root cause: `_skip_push()` only skipped push logic when the downstream move's source was a child-or-equal of the current move's destination (`m.location_id._child_of(self.location_dest_id)`). When the destination was changed to a sublocation (WH/Stock/Shelf 1), this check failed, so `_push_apply()` ran, found the delivery's source (WH/Stock) was not a child of WH/Stock/Shelf 1, and called `_break_mto_link()`, clearing `move_orig_ids` on the delivery move. The delivery then fell back to make-to-stock reservation and picked an unrelated lot.

### Issue
Since the introduction of the Tax Returns feature in 18.3, it was no longer possible to generate a Closing Entry as the button has been replaced by Returns
The Return mechanism implies that you need a Return Type in order to make a Closing Entry using the Validate button

Additionally, using the Generic Tax Report by default creates a risk in Multi-VAT environments, as it mixes taxes from all countries instead of isolating Peruvian taxes

### Cause
The new 18.3 accounting workflow requires at least one active Return Type associated with a country-specific report variant to display the Return options and process the closing entry Peru was relying on the Generic Tax Report, without a dedicated report variant
No Return Type was configured, which blocked Odoo's automatic VAT closing workflow and prevented the system from prompting the user to configure the required closing accounts

### Steps to reproduce
- Install `l10n_pe_reports` and `accountant`
- Switch to a PE Company
- Go to the Tax Report

Before the fix, no Returns button is available for any of the existing reports, making it impossible to use Odoo's automatic process to configure the tax accounts and trigger the closing entry

### Notes
This is fixed by creating a dedicated Peruvian tax report variant directly in Enterprise that inherits from the generic tax report A custom handler is added to force the domain filtering on Peruvian taxes only, and a corresponding Return Type is defined to restore the full closing entry process safely

Scenario:

- set up turnstile
- with recent safari mac os or ios (reproduced from 26.2) go to
  /web/login page in a private window
- enter login and password and pass the turnstile challenge
- click on Log in

Result: nothing happens and there is an error in the console "An invalid
form control with name='' is not focusable."

Cause:

By default Safari has the Settings > Advanced > "Use advanced tracking
and fingerprinting protection" set to "in Private Browsing".

If this options is enabled in private browser or in all browsing, you
can't login to Odoo with turnstile because safari is preventing the
update of the element that is preventing to send the form:

<input style="display: none;" class="turnstile_captcha_valid" required>

When turnstile challenge succeeds, a value should be set to this input
that will unlock the form, the .value property is updated but the
browser Shadow Content is not (and if we remove display:none, the input
is empty).

Fix:

I've not been able to reproduce the issue without turnstile using same
situation and iframe. We don't know Safari heuristic but the unlocking
is working if:

- we use setProperty instead of .value
- we unset required
- we remove the input
- we display the turnstile_captcha_valid input before challenge

This fix replaces setting .value by setProperty, and add a failsafe of
unsetting required.

fixes #247536

Forward-Port-Of: odoo/odoo#253367

Steps to produce:
---
- Install `sale_subscription` module.
- Enable `pricelists` from Settings.
- Create a new subscription product.
- Create a new pricelist and Under Recurring Prices, add below rules for
  the monthly recurring plan on creatred subscription product:
      - Min Qty = 0 then Price = 0.
      - Min Qty = 10 then Price = 10.
      - Min Qty = 20 then price = 20.
 (This setup ensures the product is free when the quantity is less than 10, and
 pricing increases based on the defined quantity tiers.)
- Create a sale order > Set a customer > Select the recurring plan as `Monthly` > Apply the created pricelist.
- Add the subscription product with quantity = 20 then Unit price is correctly set to 20.
- Change the quantity to 1.

Observation:
---
- The unit price does not update to 0 as expected.

Root cause:
---
- At [1], when quantity is updated to 1, `super()._get_pricelist_price()` correctly returns `0`.
- However, due to the `or self.price_unit` condition, the existing unit price is retained instead of applying the new value.
- This prevents valid pricelist rules (including zero-priced ones) from being applied.

Fix:
---
- As shown in [2], `line.pricelist_item_id` is set when a matching pricelist rule is found. Therefore, when a rule (including one for quantity = 0) applies, it will be reflected in `line.pricelist_item_id`.
- If `pricelist_item_id` is set, the computed price from the rule must be used; otherwise, fall back to the existing unit price.

#### Description of the issue/feature this PR addresses:
Opening the Asset Depreciation Schedule report with a period comparison enabled crashes with KeyError: 'no_format' when prefix grouping is active (large number of assets in one account group). The report becomes unusable for affected customers.

#### Current behavior before PR:
_regroup_lines_by_name_prefix sums each subline column by indexing prefix_subline['columns'][i]['no_format'] directly. Empty columns are built as {} by _build_column_dict (both col_value and col_data are None), so they have no 'no_format' key. With a comparison period enabled, an asset that has no value in the comparison period produces an empty column for that period; once prefix grouping fires (len(lines) >= prefix_groups_threshold, default 4000), the direct lookup hits that empty dict and raises KeyError: 'no_format'.

#### Desired behavior after PR is merged:
The prefix group total treats a missing 'no_format' as 0, matching the sibling caller in account_asset/models/account_assets_report.py that already guards with .get('no_format', 0). The report builds without crashing and the empty comparison column contributes 0 to the prefix group total.

The indeterminate checkbox is a [standard API](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/:indeterminate#:~:text=true%3B%0A%7D-,Result,-Play) (JS and CSS only as @pparidans noted), which has been implemented in Odoo in a couple of different ways, and is currently not working out-of-the-box (enterprise only): 

------
PROBLEMS: 

- Original implementation was with JS because of a (now fixed) owl issue:
see [ web/static/src/search/search_panel/search_panel.xml](https://github.com/odoo/odoo/blob/c0c82927f2e7e2a54749a0e081d8a03b9ef654e2/addons/web/static/src/search/search_panel/search_panel.xml#L99-L103) & https://github.com/odoo/owl/issues/713

- The new intended odoo-api for the indeterminate checkbox (`t-att-indeterminate` or `<Checkbox indeterminate="...")` doesn't work with enterprise installed because: `web_enterprise/static/src/scss/bootstrap_overridden.scss` sets `$component-active-color: unset !default;` & Bootstrap's uses `$form-check-input-indeterminate-color: $component-active-color` therefore resolves to `unset`, making the dash invisible.
-> This was fixed in studio only (odoo/enterprise#81372) but should apply globally.


------
FIXES: 

- Refactor the JS workaround to use the `t-att-indeterminate`, simplifying the code in `web` (with the help of owl magic)
- Apply the studio fix globally to enterprise module (we keep the studio fix with custom svg because the color pattern of studio is a bit different, so removing the custom svg makes the UI look less good).

The display name of the account.report.line in the general ledger report has the format of:

INVOICE NAME (invoice refs)

In the case where a client has hundreds of sales orders batched to a single invoice, the ref can
become extremely long, e.g.:

INV/2026/00001 (S12123, S12152, S12159, S12140, S12165, S12161, S12162, S12110, S12099, S12124, S12145, S12128, S12114, S12131, S12097, S12185, S12154, S12133, S12190, S12118, S12116, S12102, S12155, S12153, S12158, S12150, S12100, S12142, S12121, S12122, S12111, S12187, S12172, S12177, S12095, S12117, S12144, S12137, S12092, S12138, S12186, S12182, S12112, S12148, S12183, S12101, S12178, S12119, S12169, S12115, S12146, S12093, S12126, S12160, S12163, S12129, S12098, S12151, S12096, S12174, S12120, S12130, S12147, S12180, S12191, S12164, S12141, S12105, S12136, S12139, S12109, S12106, S12104, S12103, S12175, S12179, S12188, S12113, S12173, S12167, S12171, S12134, S12094, S12184, S12166, S12170, S12125, S12135, S12143, S12176, S12189, S12156, S12181, S12107, S12157, S12132, S12149, S12127, S12108, S12168...)

Because the length of the account.report.line is unchecked in account_general_ledger.py label
builder, the pdf can clog to one or two account.report.lines per page, skyrocketing the pdf page length.

As wkhtmltopdf processes the report from html to pdf it makes a system call openat() to the /tmp/report.footer.tmp.x.html file for EACH page of the pdf. You can see the TODO comment in the spoolTo function in wkhtmltopdf (both in Odoo and the original repo) saying that the header and footer need to be freed, on each page processing, not just null pointed.

https://github.com/odoo/wkhtmltopdf/blob/2c884bd1545b8a639847de22f24754ee5a6fc44c/src/lib/pdfconverter.cc#L794

I verified that that the number of openat calls to the /tmp/report.footer.tmp.x.html file equals the exact number of pages in the pdf to be generated if the report HAD generated successfully by setting the footer input into
_run_wkhtmltopdf to None, generating the report without footers, then separately running an strace on wkhtmltopdf when the report fails to generate. See related ticket linked at bottom.

The linux machine used on sh instances has a ulimit -n of 1024 file descriptors. Because
the footer file descriptors accumulate, once a pdf has about 1010+ pages (~a dozen fd's are allocated for other purposes), over 1024 file descriptors are opened and the system fails with:

Wkhtmltopdf failed (error code: -6). Message:
QEventDispatcherUNIXPrivate(): Unable to create
thread pipe: Too many open files
QEventDispatcherUNIXPrivate(): Can not continue
without a thread pipe

Since wkhtmltopdf is archived and Odoo has a replacement in development, I suggest that we limit the display_name of the account.report.line to 200 to keep the bloat minimized, preventing one account.report.line's name from taking up an entire page of the general ledger pdf. This allows many more batched invoices to be shown in the report and a much greater time range of data to be printed without hitting the fd limit.

I suggest changing it at the general ledger report level rather than in the account.move.line
_compute_display_name function, as we probably still want to see the full display_names at the invoice level.

On runbot, the machine has different memory constraints than on sh / local, so it hits the following error before the one above:

Wkhtmltopdf failed (error code: -11). Memory limit too low or maximum file number of subprocess
reached. Message :

Steps to Reproduce on 19.0 newdb:

1. newdb -n test_gl -v 19.0
2. ensure ulimit is set to 1024 in shell that runs odoo instance by running ulimit -n 1024 to
mimic ulimit of sh environment
3. run db with python3 odoo-bin, ensuring high enough memory constraints to simulate multi
worker sh instance, i.e.
--limit-memory-soft=12884901888
--limit-memory-hard=1288490188
4. install sales, accounting, stock
5. install demo data
6. create invoices with 100+ associated sales orders
7. generate the pdf
8. Increase the amount of invoices till the general ledger page count hits ~1010+, where you will
hit the error.

closes #118067

### Steps to reproduce:

1. Create a product tracked by lot
2. Put 10 units in WH/Stock without lot
3. Inventory > Operations > Adjustments > Physical Inventory
4. Select the line referring to your product and request an inventory count + Show Expected Quantity
5. Open the barcode app > Count Inventory
6. Scan your product
#### > The line is not selected, in particular, next scans will be re-interpreted as product scans rather than new serial creation for your product.

### Cause of the issue:

Scanning your product search a line to select if any: https://github.com/odoo/enterprise/blob/bce04ce24b66fb1a2481274eb3aebdc30a62766e/stock_barcode/static/src/models/barcode_model.js#L1432-L1435 https://github.com/odoo/enterprise/blob/bce04ce24b66fb1a2481274eb3aebdc30a62766e/stock_barcode/static/src/models/barcode_model.js#L1630-L1632
However, the `findLine` will fail since this method calls the `_canOverrideTrackingNumber` to determine if the lot of the barcodData matches the one of the line:
https://github.com/odoo/enterprise/blob/bce04ce24b66fb1a2481274eb3aebdc30a62766e/stock_barcode/static/src/models/barcode_model.js#L1859-L1863
But, the override of the `_canOverrideTrackingNumber` method for the `BarcodeQuantModel` does not handle the absence of lotName in the barcodeData correctly as it does not consider that a line without lot can be overridden by an empty lotName:
https://github.com/odoo/enterprise/blob/bce04ce24b66fb1a2481274eb3aebdc30a62766e/stock_barcode/static/src/models/barcode_quant_model.js#L729-L731
Note however that the super call does:
https://github.com/odoo/enterprise/blob/bce04ce24b66fb1a2481274eb3aebdc30a62766e/stock_barcode/static/src/models/barcode_model.js#L795-L798

### Issue 2:

### Steps to reproduce:

- Steps 1 -> 5
- Click on your product line to select it
- Scan a new lot to add one new unit referring to that lot
- Confirm (1)
- Apply Now
#### > User Error: Quant's editing is restricted, you can't do this operation

Since the line is selected, you have a currentLine during the `processBarcode` and hence the existing line will be updated using the `lotName``:
https://github.com/odoo/enterprise/blob/cf3c2fce8a6b7b2d7547d44a0e4423f887986d52/stock_barcode/static/src/models/barcode_model.js#L1560-L1584 However, writing on the line will then try to write on the related quant during the validation process which will be forbiden since we are not allowed to change the lot of an existing quant:
https://github.com/odoo/odoo/blob/e3b0ca11d99b2ef819cdad68b169112cd73668b6/addons/stock/models/stock_quant.py#L351-L360 Now, the issue is that actually due to the nature of the line and of the barcode data, the line lot is not expected to be updated but rather a new line is expected to be created:
https://github.com/odoo/enterprise/blob/cf3c2fce8a6b7b2d7547d44a0e4423f887986d52/stock_barcode/static/src/models/barcode_model.js#L795-L798

Additional issue:

Fixing issue 1 and 2 highlight and other issue of the validation process:

- Steps 1 -> 6
> The line gets selected
- Scan a newlot
> a new subline is added referring to 1 unit of your new quant
- Confirm (1) > Some serials where not counted, set them as missing
#### > Check your quants: the 10 unit lotless quant was not updated but a new quant for 1 units was created for your newlot

### Cause of the issue:

Applying all quantities is expecting to toggle them as counted before applying to update the existing quants:
https://github.com/odoo/enterprise/blob/c8535a7a0e2eae811048a34a0bae187a1fa45311/stock_barcode/static/src/models/barcode_quant_model.js#L72-L82 https://github.com/odoo/enterprise/blob/c8535a7a0e2eae811048a34a0bae187a1fa45311/stock_barcode/static/src/models/barcode_quant_model.js#L287-L296 However, only line tracked by serial numbers are set as counted: https://github.com/odoo/enterprise/blob/c8535a7a0e2eae811048a34a0bae187a1fa45311/stock_barcode/static/src/models/barcode_quant_model.js#L60-L63

### Issue before this commit:
In accrual reports (e.g., "Bill To Receive", "Billed Not Received", "Invoices To Be Issued", and "Invoices Not Delivered"), when grouping the list view by fields such as Vendor, the group header totals for the "Received", "Billed", and "Amount" columns display 0.00 even if the interanl lines of the group are not 0.00.

### Steps to reproduce the issue:
1. Download Purchase Accounting and Sale Accounting
2. Go to one of this pages: Billed Not Received, Bill To Receive, Invoices To Be Issued, and Invoices Not Delivered
3. Ensure the view is in its default grouping (grouped by Vendor or Customer)
4. Observe the group header rows for the Received (or Delivered), Billed (or Invoiced), and Amount columns. They all display 0.00
5. Expand a group that contains records with values greater than zero
6. Observe that the individual records populate correctly, but the aggregated group header row continues to display 0.00.

### Cause of the issue:
The commit ddc1b681656ea8c70f3231cda20b5a58b9ff7dd6 adapted the code to retrieve the new accrual reports but attempted to fetch grouped records using group[0].id as the dictionary key, while the grouped() method actually used the recordset object as the key. This mismatch caused the dictionary lookup to fail, resulting in 0.00 sums. https://github.com/odoo/enterprise/blob/c8535a7a0e2eae811048a34a0bae187a1fa45311/account_accountant/models/analytic_mixin.py#L40-L48

### Reason to introduce the fix:
This fix restores the core analytical utility of the accrual reports, which are crucial for accountants during period-end closings to evaluate totals at a glance.

Steps to Reproduce
---
1. Open the Planning module
2. Create an open shift with allocated_hours
3. Click Auto Plan
4. Click Undo on the auto-plan notification

Issue
---
Undoing an auto-plan operation triggers recomputation of allocated_hours,
causing the shift to lose its original workload value.

Current Behaviour
---
When resource_id is set to False during undo:
- _compute_allocated_hours is triggered (depends on resource_id)
- _compute_allocated_percentage is triggered (depends on allocated_hours)
- Both fields are recalculated, potentially changing allocated_hours
  from its pre-assignment value

Expected Behaviour
---
Undoing auto-plan should preserve allocated_hours at its pre-assignment
value while allowing allocated_percentage to adapt to the new context
(open slot vs assigned resource).

Fix
---
Use protecting context manager in action_rollback_auto_plan_ids
to prevent allocated_hours from being recomputed when resource_id is
removed. This allows allocated_percentage to recalculate naturally based
on slot duration while keeping allocated_hours stable.

## Issue
In the *Data Cleaning* app, when grouping records, the record IDs are summed up and appear right next to the name of each group, which:
1. truncates the name and count of the groups
2. does not make sense (summing up IDs is pointless)

<img width="709" height="374" alt="6166623-before" src="https://github.com/user-attachments/assets/9d80b1ec-49c0-4b7f-8c6e-53846f9e433e" />

## Steps to reproduce
1. Install *Data Cleaning* (`data_cleaning`)
2. In Data Cleaning > Configuration > Field Cleaning, create a new rule (or edit an existing one):
    - Any name
    - Model: *Contact*
    - Rule:
        - Field to Clean: *Name (Contact)*
        - Action: *Set Type Case* - Case: *All Uppercase*
4. Click the *Clean* button in the upper left corner
5. In Data Cleaning > Field Cleaning, group the records by any field (e.g., *Field*)
6. **The name of the group (_Name (Contact)_) is truncated, making it and the record count unreadable. This is due to the sum of _Record ID_ being displayed in the same row, even though that information is irrelevant.**

## Cause
The *Record ID* (`res_id`) field is an Integer field defined [here](https://github.com/odoo/enterprise/blob/3603afdd5c0d19c9276f3855156be4040ab5717d/data_cleaning/models/data_cleaning_record.py#L20). By default, Integer fields have the `sum` aggregator:

https://github.com/odoo/odoo/blob/681610c002a310f1c73fc2e5bec8d3dae27bc4a7/odoo/orm/fields_numeric.py#L17-L23

This causes the IDs to be summed up and appear in the group headers.

### Issue
Since the introduction of the Tax Returns feature in 18.3, it was no longer possible to generate a Closing Entry as the button has been replaced by Returns
The Return mechanism implies that you need a Return Type in order to make a Closing Entry using the Validate button

Additionally, using the Generic Tax Report by default creates a risk in Multi-VAT environments, as it mixes taxes from all countries instead of isolating Peruvian taxes

### Cause
The new 18.3 accounting workflow requires at least one active Return Type associated with a country-specific report variant to display the Return options and process the closing entry Peru was relying on the Generic Tax Report, without a dedicated report variant
No Return Type was configured, which blocked Odoo's automatic VAT closing workflow and prevented the system from prompting the user to configure the required closing accounts

### Steps to reproduce
- Install `l10n_pe_reports` and `accountant`
- Switch to a PE Company
- Go to the Tax Report

Before the fix, no Returns button is available for any of the existing reports, making it impossible to use Odoo's automatic process to configure the tax accounts and trigger the closing entry

### Notes
This is fixed by creating a dedicated Peruvian tax report variant directly in Enterprise that inherits from the generic tax report A custom handler is added to force the domain filtering on Peruvian taxes only, and a corresponding Return Type is defined to restore the full closing entry process safely

### Cause of the issue:

Since the uom used on the quant is archived, it is not found by the search used to fill the barcodeCache:

Currently when user adds adds quantity in barcode using lots it leads to incorrect sale order quantities.

## Steps to replicate:
- Install Sales and Barcode (no demo data).
- Enable Lots & Serial Numbers in settings.
- Create Test Product with Tracking by Lots.
- Go to Inventory > Products>Lots & Serial Numbers and create 3 lots for the product.
- Update each lot’s on-hand quantity to 10 from the product page.
- Create and confirm a Sales Order for the product (lines: qty 3 and 2 units).
- Open the delivery in the Barcode app:
   - Scan lot 2 > increase qty to 3 using +1 button
   - Scan lot 3 > increase qty to 2 using +1 button
- Validate and go to the sale order.

## Observed Behavior:
The sale order delivered quantities are flipped and a backorder is created even though the quantity for the product is satisfied.

## Root cause:
The issue occurs because when a sales order is confirmed, the system defaults to
 using lot 1 on the delivery receipt. When a user scans lot 2, the `_processBarcode` function is triggered, which calls `_findLine` at [1] to select the appropriate line on the receipt.

As the loop in `_findLine` iterates through `pageLines` with values like: 
```
[{display_name: "Test product", quantity: 3, lot_id: { name: 'lot1' }}, 
{display_name: "Test product", quantity: 2, lot_id: { name: 'lot1' }}]
```

During the first iteration, `foundLine` is set at [2] for the line with quantity 3 . Since the subsequent if condition is not satisfied, the loop hits the continue block at [3].
On the next iteration, the line with quantity 2 causes `foundLine` to be overwritten at [2], and the continue block is executed again at [3].

This results in the line with quantity 2 being selected as the line to update at the end of the function.

When the user manually increases the quantity to 3, the line that originally required quantity 2 is updated and fulfilled.
Later, when lot 3 is scanned, the line that required quantity 3 is selected for update, and manually increasing the quantity to 2 before validating the order leads to a backorder and causes the delivered quantities to be flipped.

## Solution:
Avoid grouping lines from different moves unless using batch transfers. This ensures that backorders are not created when the barcode lines are fulfilled.

**Description of the issue/feature this PR addresses:**

When generating a SEPA QR code for a vendor bill payment, the embedded 
amount could occasionally contain excess decimal places instead of 
respecting the currency's expected precision.

This occurs because the `amount` variable in `_get_qr_vals` was being 
converted directly using `str(amount)`. Due to Python's floating-point 
arithmetic, the float value in memory can contain decimal drift.
Directly casting it to a string exposes this drift in the payload.

This commit resolves the issue by replacing `str(amount)` with 
`float_repr(amount, currency.decimal_places)`. This safely bypasses 
the float representation issue, ensuring the string strictly respects 
the currency's configured decimal precision before being injected 
into the QR code.

opw-5504258

**Steps to reproduce:**

- Select company “My Belgian Company”
- Create a 23% purchase tax
- Create vendor bill
   - Select Vendor “BE Company CoA”
   - Choose any single product, change price to 37.18 and choose the 23% tax. The Untaxed Amount should be 37.18, VAT tax should be 8.55, and Total should be 45.73
   - Confirm > Register Payment > scan QR code. EUR45.730000000000004 should show

**Current behavior before PR:**

- When generating a SEPA QR code for a payment, the embedded amount can contain excess decimal places due to floating-point drift.

**Desired behavior after PR is merged:**

- The SEPA QR code is generated with the correct number of decimal places.

Steps to produce:
---
- Install sale_management and website_sale modules with demo data.
- From settings, disable the PDF Quote Builder.
- Go to Settings > Technical > Sequences & Identifiers > External Identifiers.
- Delete the `consu_delivery_02_product_template` identifier.
- From settings, try to enable the PDF Quote Builder again.

Issue:
---
```py
insert or update on table "quotation_document_sale_pdf_form_field_rel" violates foreign key constraint
"quotation_document_sale_pdf_form_fie_quotation_document_id_fkey"
DETAIL: Key (quotation_document_id)=(1) is not present in table "quotation_document".
```


Cause:
---
When the XML demo loader processes **`sale_pdf_quote_builder_demo.xml`**, it calls `create()` on `quotation.document` for each of the 5 demo records one by one. Each create() call receives vals_list that contains datas, the actual PDF base64 content.

Inside `super().create(vals_list) `[1], the ORM writes datas to `ir_attachment`. Since `form_field_ids` is a `store=True` computed field with `@api.depends('datas')` [2], the ORM knows it needs to recompute `form_field_ids`. But it does not run the computation immediately. It simply registers the records in a pending recompute set and moves on. Nothing hits the DB yet for this compute.

After `super().create() `returns, the `write({'res_model': ..., 'res_id': ...})` runs. Since `res_model` and `res_id` live on `ir_attachment` (the parent table via _inherits), this write is also not immediately flushed to the DB. The ORM marks it as dirty in the cache and defers it.

So after all 5 records are created, the ORM holds two deferred things: a dirty UPDATE ir_attachment write for all 5 records, and a pending recompute for `form_field_ids` on all 5 records. Nothing has been flushed to the DB yet.

When the demo XML tries to reference `product.consu_delivery_02_product_template` [3], which no longer exists,
a ValueError is raised. From `load_demo()` [4], the savepoint is rolled back.

After the except block logs the failure, execution continues in l`oad_module_graph()` which calls `env.cr.commit()`. This triggers f`lush() -> transaction.flush() -> flush_all() -> _recompute_all()`. The ORM processes the pending recompute registry and finds `form_field_ids` needs recomputing for quotation.document(1, 2, 3, 4, 5). It calls `_compute_form_field_ids`() on those stale ids. Inside that compute, `_create_or_update_form_fields_on_pdf_records()` tries to insert into `quotation_document_sale_pdf_form_field_rel` with quotation_document_id=1. But quotation_document id 1 no longer exists in the DB — it was rolled back — so PostgreSQL raises the foreign key violation.

This is confirmed by the traceback from `_compute_form_field_ids`, which shows the call chain going through `commit() -> flush_all() -> _recompute_all()` rather than through `create()`, proving the compute fired after the rollback using stale ORM cache state.

Fix:
---
Calling `docs.flush_recordset()` at the end of `create()` forces all pending writes and pending recomputes to be executed immediately, while still inside the savepoint scope:

- It flushes the dirty res_model/res_id write on the ir_attachment parent table, so UPDATE ir_attachment hits the DB inside the savepoint.
- It triggers `_recompute_all()` for the pending `form_field_ids` compute on docs, so `_compute_form_field_ids()` runs inside the savepoint and the INSERT into `quotation_document_sale_pdf_form_field_rel` happens while the quotation_document rows still exist in the DB.

If the savepoint then rolls back, the ORM cache has nothing dirty or pending left. The subsequent commit() in `load_module_graph()` finds nothing to flush, so no stale writes execute against non-existent ids and no foreign key violation occurs.
