**_Steps to reproduce :_**

-  Install l10n_it_riba.
-  Configure a company with a San Marino (SM) IBAN as the bank account for the
   journal used for Ri.Ba.
-  Create a customer payment and add it to a Batch Payment using the Ri.Ba.
   payment method.
-  Validate the Batch Payment.

**_Observed behavior :_**

 The validation fails with the error:
   `Only bank accounts with an Italian IBAN are allowed to use Ri.Ba. payments`

**_Cause :_** 

 The Ri.Ba. validation logic only accepts IBANs with the IT country code and incorrectly rejects valid San Marino (SM) IBANs.

**_Fix :_**

-  Update the Ri.Ba. IBAN validation to accept both Italian (IT) and San Marino (SM) IBANs when generating Ri.Ba. payment files.

-  While validating Batch Payments for SM IBANs, we observed that the extracted value could overlap with the branch code portion, causing the generated RIBA record to exceed the expected 120-character length. This change updates the extraction logic to prevent overlap and ensure compliance with the required record format.

### Description of the issue/feature this PR addresses

Sending the **Partner Ledger** report by email in a multi-currency setup (several companies using different currencies) crashes the send wizard on opening with:

```
psycopg2.errors.UndefinedTable: relation "account_currency_table" does not exist
```

### Current behavior before PR

To compute the recipients, `AccountPartnerLedgerReportHandler._get_report_send_recipients` runs `_get_query_sums`, whose SQL joins the currency table. In a multi-currency setup that table is a **temporary** table that must be created beforehand by `AccountReport._init_currency_table`.

Every regular rendering entry point calls `_init_currency_table` before running currency-table queries, but the report-sending path does not, so the query fails on a missing `account_currency_table` relation.

### Desired behavior after PR is merged

`_init_currency_table(options)` is called before running the query, so the temporary table exists. It is a no-op in mono-currency setups (early return in `_init_currency_table`), so mono-currency behavior is unchanged.

### Steps to reproduce

1. Have several companies using different currencies.
2. Select more than one of them in the company switcher.
3. Open **Accounting > Reporting > Partner Ledger**.
4. Click **Send by email** → the wizard crashes on opening.

### Issue:

Attributes of DoctoRelacionado node in the XML display an incorrect value because the exchange rate difference entry distorts the calculation, even though the invoice was fully settled.

https://drive.google.com/file/d/1ntQny0o8bkkfYtY5ZNBK0Yq7Rq0I-yfz/view

### Fix:
Sorting partials by "not exchange_move_id" first broke the chronological order whenever the invoice/payment partial itself carried an exchange difference (e.g. a foreign currency payment settled at another rate). This made the residual-chain algorithm consume the credit note's "other_residual" on the wrong payment, so ImpSaldoAnt/ImpPagado/ ImpSaldoInsoluto in the payment CFDI's DoctoRelacionado stayed wrong even though the invoice was fully paid.

Populate the exchange move mapping in a separate first pass and sort the partials purely by date/id, so credit notes are always deducted from the correct payment.

Steps to reproduce:
- Configure a preparation display on a POS config with a product category
- Place an order and leave it in a non-final stage
- Keep the session open past midnight

Issue:
The kanban order-count badge drops the order once its create_date falls behind "today", while the preparation screen still lists it. The same divergence makes the badge keep counting an order that a "Reset" already removed from the screen.

_compute_order_count() scoped its search on pos_config_id and create_date >= today, whereas the screen is built by get_preparation_display_order() from _get_open_orders_in_display() and _get_stageless_orders_in_display(), which have no date filter and instead bound the set by the order stage `done` flag and the session state. An order open across midnight is therefore in the screen set but not in the badge set. Conversely reset() marks the current stage done, which drops the order from the screen set, but the badge only skipped orders whose latest stage is the final stage, so an order reset while still in the first stage stayed counted.

    raise ValueError("Expected singleton: %s" % record)
ValueError: Expected singleton: res.partner(9, 8, 7)
```
Cause:
---------
https://github.com/odoo/enterprise/blob/38674448e387159d28f98c1678856fcaf5f7f52e/documents_hr/models/hr_employee.py#L23-L48
1. The document count computation assumes all employees belong to the same company by directly accessing `self.company_id.documents_hr_settings`. In a multi-company environment, `self` may contain employees from different companies, making self.company_id a multi-recordset and triggering a singleton error.

2. Similarly, when `documents_hr_settings` is disabled, the fallback computation accesses `self.work_contact_id` on a multi-recordset, causing another singleton error.

Solution:
-----------
Split the employees based on whether `documents_hr_settings` is enabled and compute each group separately.
Additionally, use the current employee's `work_contact_id` in the fallback computation to avoid singleton error.

**NOTE:**
This has been resolved from saas-19.4 onward with this improvement [commit](https://github.com/odoo/enterprise/commit/d018d8205300b434728129e199ae048cefbaa296).

When setting an account to an account.bank.statement there is a step to automatically create a reconciliation rule/model if one does not exist already. To do so, we retrieve 5 account.bank.statement.lines and use them to define the reconciliation model config. A matching is done on the payment_ref of the account.bank.statement.lines by finding the longest common substring in the reference.

### Current Implementation
The current algorithm does so by first generating all the possible substrings for all the payment_ref before doing the intersection between these sets and returning the max if `len(substring) >=10`. This is reasonable when the payment_ref follows either a SEPA communication national standard like the Belgian one or the Creditor Reference standard (ISO 11649). For transactions with large, unstructured communication with more than 100 chars, the method `_get_common_substrings` quickly overfill the memory, sometimes raising a MemoryErorr, and takes a significant amount of time. That's because the nested function `_generate_all_substrings` generates n*(n+1)/2 substrings, with n being the lenght of a payment_ref, called `label` in `generate_all_substrings`.

### Proposed Fix
This commit introduces another algorithm to find the largest common substring. It starts by taking the two smallest labels to find their substrings intersection. We know that for an arbitrary collection of labels, the intersection of their substrings sets A ∩ B ∩...∩ Z is included in the intersection of any two substrings sets. The underlying assumption of the first step is that for an arbitrary collection of labels the intersection of the substrings sets of the two smallest labels will be the smallest intersection of any given pair of substrings sets. This won't hold true everytime and using a metric such as label similarity instead of shortest string might be better. But on average this should be good enough and it's easier to implement + it removes the need of preprocessing the labels to compute the similarity.

The point of the new nested function `common_substrings` is to discard common substrings as we build them. Using the current `generate_all_substsrings` on either the smallest label or both smallest
labels would still generate and store a lot of substrings, especially for large labels. By yielding the common substrings as we find them, the memory footprint is vastly reduced.

Lastly, the next substring in the common_substrings iterable is only checked against the remaining labels if it's longer than the current match. This speeds up the whole process

### speedup

In a customer database with some account.bank.statement.line with payment_ref > 500 chars, setting a specific account (code 4970) on transactions goes from MemoryError to < 1Mb memory consumption.

Because of the memory consumption it was not possible to gather timing value on the current version. 
Testing the new algorithm in a shell and using as labels the 5 longest payment_ref in the customer database
(831, 831, 1117, 1178, 1300 chars), averaging to 2000 chars once normalised, the average time to execute `_get_common_substrings` is 900 ms ± 10.3 ms.

Currently, an error occurs when a user removes the Tax Treatment Category of an Australian employee.

Steps to Reproduce:
 - Install the `l10n_au_hr_payroll` module with demo data.
 - Switch to an `Australian company`.
 - Open any `Employee` > `Payroll` > remove the `Tax Treatment Category` value.

`UnboundLocalError: cannot access local variable 'code' where it is not associated with a value`

After the [change] in selection field behavior, users can clear the value of the field. When the 
user removes the Tax Treatment Category value, the system computes the tax treatment 
code [1]. During this process, if no condition matches, the code variable is not initialized. 
Converting this uninitialized variable to a string [2] raises an error.

This commit ensures that when the tax treatment category is not set, the tax treatment code is 
set to False with an early return. Since the tax treatment category is required field and compute 
the correct tax treatment code, once the category is set.

Steps to reproduce:
-------------------
1. Install Timesheets.
2. Create a new employee with a fully fixed working schedule (40h/week).
3. Open Timesheets > All Timesheets and create a new timesheet in the past week for this employee (e.g. 8 hours).
4. Observe the overtime indicator for the employee (it shows 32 hrs)
   (Click the left arrow to display it).
5. Change the timesheet encoding unit to "Days / Half-Days".
6. Return to Timesheets and observe the overtime indicator (it now correctly shows 4 days).
7. Install a language other than English (e.g. French).
8. Return to Timesheets and observe the overtime indicator again.

Issue:
--------
The remaining time value changes unexpectedly and displays 32 hours instead of 4 days.

Cause:
---------
In `get_timesheet_and_working_hours_for_employees`, the code determines whether the timesheet UoM is expressed in days by comparing the UoM name with the string `"days"`.

Since UoM names are translatable, this comparison becomes invalid when the user language changes (e.g. `"jours"` in French), causing the logic to skip the day conversion and return values in hours instead.

Solution:
-----------
Compare the timesheet UoM record with the day UoM record directly instead of relying on translated string values.

1. The document count computation assumes all employees belong to the same company by directly accessing `self.company_id.documents_hr_settings`. In a multi-company environment, `self` may contain employees from different companies, making self.company_id a multi-recordset and triggering a singleton error.

2. Similarly, when `documents_hr_settings` is disabled, the fallback computation accesses `self.work_contact_id` on a multi-recordset, causing another singleton error.

Solution:
-----------
Split the employees based on whether `documents_hr_settings` is enabled and compute each group separately.
Additionally, use the current employee's `work_contact_id` in the fallback computation to avoid singleton error.

**NOTE:**
This has been resolved from saas-19.4 onward with this improvement [commit](https://github.com/odoo/enterprise/commit/d018d8205300b434728129e199ae048cefbaa296).

Steps to reproduce:
- Configure a preparation display on a POS config with a product category
- Place an order and leave it in a non-final stage
- Keep the session open past midnight

Issue:
The kanban order-count badge drops the order once its create_date falls behind "today", while the preparation screen still lists it. The same divergence makes the badge keep counting an order that a "Reset" already removed from the screen.

_compute_order_count() scoped its search on pos_config_id and create_date >= today, whereas the screen is built by get_preparation_display_order() from _get_open_orders_in_display() and _get_stageless_orders_in_display(), which have no date filter and instead bound the set by the order stage `done` flag and the session state. An order open across midnight is therefore in the screen set but not in the badge set. Conversely reset() marks the current stage done, which drops the order from the screen set, but the badge only skipped orders whose latest stage is the final stage, so an order reset while still in the first stage stayed counted.

Issue:
In accrual list reports (Billed Not Received / Invoiced Not Delivered), selecting an "As of" date, opening a line, and returning with the breadcrumb resets the date filter to the default value (today's date)

Steps to reproduce:
1) Open an accrual list report ( Accounting > Audit > Purchases > Bill to receive / Billed Not Received OR Invoices to be issues / invoiced Not delivered)
2) Pick any "As of" date
3) Open any row
4) Click breadcrumb to return to the accrual list
5) Observe the "As of" date has been reset to today's date
To generate some data you could:
create a PO, then upload the bill, validate the receipt, then you'll find it in bills received

Cause:
`AccrualListController.setup()` always initialized state.date with a fresh default date and did not re-put the previously saved `accrual_entry_date` from restored context
https://github.com/odoo/enterprise/blob/899f0d45b2ae1dc4e5e06a2e0acb3d006d12d563/account_reports/static/src/views/accrual_list_controller.js#L10-L16

Although `setDate()` stored the selected date in context, `setup()` overwrote the UI state on controller recreation
https://github.com/odoo/enterprise/blob/899f0d45b2ae1dc4e5e06a2e0acb3d006d12d563/account_reports/static/src/views/accrual_list_controller.js#L61-L65

Solution:
- Persist `accrual_entry_date` in `AccrualListSearchModel` via `exportState()` / `_importState()`, so the date is restored in search context before the list model loads on breadcrumb navigation.
- Initialize the date picker through `setDate()` in `onWillStart()` instead of hardcoding `DateTime.now()` in `setup()`, so restoration and user changes share the same code path.
- In `setDate()`, reset grouped list caches (`currentGroups` and `groups`) before `root.load()`, because those caches are not keyed on `accrual_entry_date` and would otherwise show stale vendor groups after a date change or breadcrumb restore.

### Description of the issue/feature this PR addresses

Sending the **Partner Ledger** report by email in a multi-currency setup (several companies using different currencies) crashes the send wizard on opening with:

```
psycopg2.errors.UndefinedTable: relation "account_currency_table" does not exist
```

### Current behavior before PR

To compute the recipients, `AccountPartnerLedgerReportHandler._get_report_send_recipients` runs `_get_query_sums`, whose SQL joins the currency table. In a multi-currency setup that table is a **temporary** table that must be created beforehand by `AccountReport._init_currency_table`.

Every regular rendering entry point calls `_init_currency_table` before running currency-table queries, but the report-sending path does not, so the query fails on a missing `account_currency_table` relation.

### Desired behavior after PR is merged

`_init_currency_table(options)` is called before running the query, so the temporary table exists. It is a no-op in mono-currency setups (early return in `_init_currency_table`), so mono-currency behavior is unchanged.

### Steps to reproduce

1. Have several companies using different currencies.
2. Select more than one of them in the company switcher.
3. Open **Accounting > Reporting > Partner Ledger**.
4. Click **Send by email** → the wizard crashes on opening.

Steps to reproduce:
-------------------
1. Install Timesheets.
2. Create a new employee with a fully fixed working schedule (40h/week).
3. Open Timesheets > All Timesheets and create a new timesheet in the past week for this employee (e.g. 8 hours).
4. Observe the overtime indicator for the employee (it shows 32 hrs)
   (Click the left arrow to display it).
5. Change the timesheet encoding unit to "Days / Half-Days".
6. Return to Timesheets and observe the overtime indicator (it now correctly shows 4 days).
7. Install a language other than English (e.g. French).
8. Return to Timesheets and observe the overtime indicator again.

Issue:
--------
The remaining time value changes unexpectedly and displays 32 hours instead of 4 days.

Cause:
---------
In `get_timesheet_and_working_hours_for_employees`, the code determines whether the timesheet UoM is expressed in days by comparing the UoM name with the string `"days"`.

Since UoM names are translatable, this comparison becomes invalid when the user language changes (e.g. `"jours"` in French), causing the logic to skip the day conversion and return values in hours instead.

**Steps to reproduce:**
- Install the `l10n_pl_reports` module and switch to a `PL Company`.
- Create and confirm a vendor bill with a `Bill Reference` and `Taxes`.
- Navigate to Accounting > Reporting > Tax Report and select `This Month`.
- From the dropdown, click `JPK` > `Export XML`.
- Open the generated XML file and observe the `DowodZakupu` field.

**Observation:**
`DowodZakupu` contains the vendor `Bill Number` even 
when a `Bill Reference` is set.

**Root Cause:**
At [1], `DowodZakupu` is populated only with the vendor `Bill number`(`move_name`) 
instead of using the `Bill reference`(`ref`) when available.

**Fix:**
This commit ensures `DowodZakupu` contains the `Bill Reference`
when it is available in JPK exports.

## Issue
The tour `test_l10n_se_pos_01` does not consistently create its `pos_order`. This leads to the following assert failing:

### Steps to reproduce:

- In the settings enable: Multi-Steps Routes and rental transfers
- Unarchive the MTO route
- Create a rental product P with a buy route and a set vendor
- Create a rental order for 1 x P and set the the MTO route on the sol
- Confirm the order
#### > The delivery as well as the purchase for 1 unit of P was generated but the return was not.

### Cause of the issue:

The procurement generated to handle both the delivery and the return rental picking are handled by the `_create_procurements`: https://github.com/odoo/enterprise/blob/b0e48baaf99bdc4faefd2ffdd3bd5637fb548593/sale_stock_renting/models/sale_order_line.py#L353-L374 The `route_ids` set and used is the `mto_route` set on the sol: https://github.com/odoo/odoo/blob/0f061503e26ac8c441d62d91947419119e48c47a/addons/sale_stock/models/sale_order_line.py#L415-L422 https://github.com/odoo/odoo/blob/0f061503e26ac8c441d62d91947419119e48c47a/addons/sale_stock/models/sale_order_line.py#L282-L297
However, in the present case, the mto  route does not contain any rule with a relevant `location_src_id` in the rental location so that the return will not be generated.

Step To Reproduce:
- Install the Accounting module.
- Go to Accounting -> Configuration -> Accounting Reports -> Generic Tax Report.
- Set the Root Report to "Balance Sheet" and save.
- Remove the Root Report and save again.
- Open Accounting -> Reporting -> Journal Audit.

Issue:
Opening the Journal Audit report raises an Internal Server Error with: psycopg2.errors.UndefinedTable: missing FROM-clause entry for table "account_move_line__move_id"

Reason:
The code that recreates the missing "account.move" join was not updated consistently with the other "_join()" usages. Without calling "._sudo()", the ORM builds the join using a filtered subquery (for example, adding the company filter), which changes the generated join alias(https://github.com/odoo/odoo/blob/saas-19.1/odoo/orm/fields_relational.py#L559). The SQL query still references the regular alias (account_move_line__move_id), causing the query to fail.

Reference PR:- https://github.com/odoo/enterprise/pull/101230

Solution:
Use "query.table._sudo()._join()" when recreating the missing "account.move" join, matching the other "_join()" usages and ensuring the expected join alias is generated.

before fix:-
`'account_move_line__move_id__2': (SQL('JOIN'), SQL('(SELECT "account_move".* FROM "account_move" WHERE "account_move"."company_id" IN %s)', (1,)), SQL('"account_move_line"."move_id" = "account_move_line__move_id__2"."id"'))`

Query : `JOIN (
    SELECT
        account_move.*
    FROM account_move
    WHERE account_move.company_id IN (1)
) AS account_move_line__move_id__2
    ON account_move_line.move_id = account_move_line__move_id__2.id`

after fix:-
`'account_move_line__move_id': (SQL('JOIN'), SQL('"account_move"'), SQL('"account_move_line"."move_id" = "account_move_line__move_id"."id"'))`

### Steps to Reproduce:
1. Activate l10n_de
2. Navigate to the General Ledger and export the "Datev DATA"
3. Column D, "Kurs," is incorrect

### Description of the issue/feature this PR addresses: 
**Issue:** DATEV documentation states that the column for "Kurs" should be the ratio of WKZ-Umsatz : WKZ-Basisumsatz, which is Foreign : Base Currency. Additionally, all sample files show this column's values being rounded to 6 decimal places. Currently, when Odoo exports the general ledger as DATEV data, there is no rounding of decimal places and the formula does base / foreign amount, `line_amount / line_amount_currency`.

**Solution:** In the `datev_export_csv.py` file, the relevant method is called `_l10n_de_datev_get_csv()`. In there, we can fix the line to round the value of `line_amount_currency / line_amount` to 6 decimal places.

### Current behavior before PR: 
Exporting the general ledger as DATEV data currently gives the reverse foreign currency rate and fails to round to 6 decimal places, which causes some values to be extremely long.

### Desired behavior after PR: 
The csv files should output the correct rate and be rounded appropriately.

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

When adding a custom field (e.g., via Studio) to the Documents list view, clicking the cell directly does not trigger inline edit mode. The user has to first click a standard editable field (like "Owner") to put the row into edit mode before they can modify the custom field.

This occurs because we use a hardcoded whitelist (`editableColumns`) of standard fields allowed to trigger edit mode. Custom fields (`x_`) are missing from this static list.

This commit resolves the issue by dynamically injecting visible, non-readonly custom fields into the `editableColumns` whitelist. This allows user-created fields to be edited inline as expected.

**Steps to reproduce:**

- Documents > Studio > List view > Add any field that accepts user input (e.g. Text/char) > save/exit
- In the same Documents list view > select a row > click the cell belonging to the newly created field > observe that the row does not enter edit mode
- In the same Documents list view > select a row > click a standard editable cell, then click the cell belonging to our newly created field > observe that this then allows us to edit our field

**Current behavior before PR:**

- Custom fields do not trigger inline edit mode

**Desired behavior after PR is merged:**

- Custom fields trigger inline edit mode

purpose:
1- We should have a consistent way to compute `_gantt_unavailability` of employees in time off and attendance. Currently, some cases have inconsistent behavior such as out of contract days, flexible and fully flexibe employees.
2- In time off calendar view, if the employee does not have a contract at all, the current working schedule will appear in the calendar and it will not be greyed out. This is inconsistent with the behavior of the attendance application.

Fix:
1. 
- implemented `_get_employee_unavailable_intervals` in employee model to be used in both time off and attendance.
    - more optimized than the old implementation in time off as it calls `_work_intervals_batch` once per calendar instead of calling it for each contract in `_unavailable_intervals_batch`
    - greys out "out of contract" periods
    - for flexible and fully flexible employees, the whole period is considered available except leave periods
- made `_get_calendar_periods` use version date start instead of contract date start and corrected a bug in tz conversion
2. 
- made `_get_unusual_days` return True for all the days outside of contracts for the employee instead of not returning anything for them or getting values from the working schedule of the employee (means that they will be greyed out in the callendar view) and added a test for it

Steps to reproduce:
- set the company currency to XCG
- set the PoS sales journal currency and the PoS pricelist currency to USD
- configure a XCG <-> USD rate
- create a customer without any outstanding balance
- open the PoS, create an order of USD 100 and validate it with the Customer Account (Pay Later) payment method
- open the Customers screen and look at the Total Due of that customer

Issue:
The Total Due shows about USD 55.56, i.e. the amount converted once too many, instead of the expected USD 100.

Cause:
get_total_due() sums two amounts that are not expressed in the same currency before converting them. partner.total_due comes from the accounting entries, it is the sum of account.move.line.amount_residual and is therefore in company currency, while total_settled is the sum of pos.payment.amount of the still open sessions, which is in the currency of the order, so the PoS one. The addition is done first and the result is then converted from the company currency to the PoS one, so the pay later payments end up converted a second time.

**Problem:**
When an appointment is cancelled, the cancellation email is always sent in the organizer's (staff member's) language, ignoring the booking customer's language. The booking confirmation, by contrast, is correctly localized.

**Steps to reproduce:**
1. Set a contact's language to a non-default one (e.g. Romanian).
2. Book an appointment for that contact (they are the booker/attendee).
3. Cancel the appointment.
4. The customer received the confirmation in Romanian but the cancellation email arrives in English.

**Current behavior:**
The cancellation email is rendered in the organizer's language.

**Expected behavior:**
The cancellation email is rendered in the booking customer's language, like the confirmation/invitation email.

**Cause of the issue:**
The cancellation uses `appointment_canceled_mail_template`, whose `lang` is `{{ object.partner_id.lang }}`. On `calendar.event`, `partner_id` is `related='user_id.partner_id'`, i.e. the organizer, not the customer. The template is posted once per event (via `_track_template`), so its single rendering language applies to every recipient, including attendees whose own language differs. The confirmation email is unaffected because it is the per-attendee `attendee_invitation_mail_template` (model `calendar.attendee`), rendered once per attendee in that attendee's language.

**Fix:**
Deriving the language from `appointment_booker_id` makes the cancellation consistent with the other appointment mails, which are meant for the person who booked the meeting. It falls back to `partner_id` when there is no booker (e.g. an event not created through the appointment flow), preserving the previous behavior in that case.

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

When adding a custom field (e.g., via Studio) to the Documents list view, clicking the cell directly does not trigger inline edit mode. The user has to first click a standard editable field (like "Owner") to put the row into edit mode before they can modify the custom field.

This occurs because we use a hardcoded whitelist (`editableColumns`) of standard fields allowed to trigger edit mode. Custom fields (`x_`) are missing from this static list.

This commit resolves the issue by dynamically injecting visible, non-readonly custom fields into the `editableColumns` whitelist. This allows user-created fields to be edited inline as expected.

**Steps to reproduce:**

- Documents > Studio > List view > Add any field that accepts user input (e.g. Text/char) > save/exit
- In the same Documents list view > select a row > click the cell belonging to the newly created field > observe that the row does not enter edit mode
- In the same Documents list view > select a row > click a standard editable cell, then click the cell belonging to our newly created field > observe that this then allows us to edit our field

**Current behavior before PR:**

- Custom fields do not trigger inline edit mode

**Desired behavior after PR is merged:**

- Custom fields trigger inline edit mode

Currently, when a quotation is created from a repair order generated from a helpdesk ticket, 
the salesperson is not set on the quotation even if the customer has a salesperson assigned.

**Steps to Reproduce:**

 - Install `helpdesk_repair`.
 - Go to `Helpdesk` > `Configuration` > `Helpdesk Teams`.
 - Open a team recod and enable `Repairs`.
 - Create a `contact/customer` with a `salesperson` assigned.
 - Go to `Helpdesk`, create a ticket for that `customer`, and select the `helpdesk team` 
   configured above.
 - Click `Repair`, then click `Create Quotation`.
 - Open the quotation and check the `Salesperson` field in the `Other Info` tab.

**Current behavior:**
The Salesperson field on the quotation remains empty.

**Expected behavior:**
The Salesperson field on the quotation should inherit the salesperson assigned to the 
selected customer/contact.

**Cause of the issue:**
When a repair order is created from a helpdesk ticket, default_user_id [1] is passed in the context . 
This value is propagated when creating the repair order [2] . Later, when creating the quotation from 
the repair order [3], the same context is reused.
Because default_user_id is already present in the context, it overrides the precomputation of user_id 
from the customer. As a result, user_id is initialized with an empty value and remains unset.

**Fix:**
This commit ensures that default_user_id is removed from the context before creating the 
sale order. Without a default value for user_id, the field is correctly precomputed from the 
selected customer, and the salesperson is properly assigned.

**Problem:**
When an appointment is cancelled, the cancellation email is always sent in the organizer's (staff member's) language, ignoring the booking customer's language. The booking confirmation, by contrast, is correctly localized.

**Steps to reproduce:**
1. Set a contact's language to a non-default one (e.g. Romanian).
2. Book an appointment for that contact (they are the booker/attendee).
3. Cancel the appointment.
4. The customer received the confirmation in Romanian but the cancellation email arrives in English.

**Current behavior:**
The cancellation email is rendered in the organizer's language.

**Expected behavior:**
The cancellation email is rendered in the booking customer's language, like the confirmation/invitation email.

**Cause of the issue:**
The cancellation uses `appointment_canceled_mail_template`, whose `lang` is `{{ object.partner_id.lang }}`. On `calendar.event`, `partner_id` is `related='user_id.partner_id'`, i.e. the organizer, not the customer. The template is posted once per event (via `_track_template`), so its single rendering language applies to every recipient, including attendees whose own language differs. The confirmation email is unaffected because it is the per-attendee `attendee_invitation_mail_template` (model `calendar.attendee`), rendered once per attendee in that attendee's language.

**Fix:**
Deriving the language from `appointment_booker_id` makes the cancellation consistent with the other appointment mails, which are meant for the person who booked the meeting. It falls back to `partner_id` when there is no booker (e.g. an event not created through the appointment flow), preserving the previous behavior in that case.

**Steps to reproduce:**
- Install the `l10n_pl_reports` module and switch to a `PL Company`.
- Create and confirm a vendor bill with a `Bill Reference` and `Taxes`.
- Navigate to Accounting > Reporting > Tax Report and select `This Month`.
- From the dropdown, click `JPK` > `Export XML`.
- Open the generated XML file and observe the `DowodZakupu` field.

**Observation:**
`DowodZakupu` contains the vendor `Bill Number` even 
when a `Bill Reference` is set.

**Root Cause:**
At [1], `DowodZakupu` is populated only with the vendor `Bill number`(`move_name`) 
instead of using the `Bill reference`(`ref`) when available.

**Fix:**
This commit ensures `DowodZakupu` contains the `Bill Reference`
when it is available in JPK exports.

### This is a revision of #119399 which had to be reverted.

Original issue
-----
Deliveries cannot be validated using DPD with Sendcloud, users get an error.

Steps to reproduce
-----
- Set up Sendcloud DPD
- Create a SO
	- Interntional customer
		- Some VAT number
	- Some product
	- Add sendcloud delivery
- Confirm SO
- Validate the linked picking

> Error: “The receiver VAT number is missing; please provide it to continue”

Issue's cause
-----
Tax numbers should be included in the `customs_information` field of the request as per the API

https://sendcloud.dev/api/v2/parcels/create-a-parcel-or-parcels#body-one-of-0-parcel-customs-information-tax-numbers

For the `vat_label` field, we have to force the language to English in the context because the field is translated by default, but sendcloud only accepts the english names (eg French "TVA" is not accepted, expected value is "VAT").

https://github.com/odoo/odoo/blob/d1d1610332a1596d026fb0a42ec236d1a79c71cc/odoo/addons/base/models/res_country.py#L75

Revert cause
-----
The vat_label field is marked for translation (translate=True)

https://github.com/odoo/odoo/blob/d1d1610332a1596d026fb0a42ec236d1a79c71cc/odoo/addons/base/models/res_country.py#L75

So if the user has the DB in french for example, we are sending "TVA" instead of "VAT" in the name field.

Other issues
-----
- We need to provide an actual fallback for `customs_invoice_nr`. As it stands, if we create a new delivery it cannot be validated because Sendcloud doesn't accept for the field to be empty.
- Same for `name`, we need to provide an actual fallback.

### Steps to Reproduce:
1. Activate l10n_de
2. Navigate to the General Ledger and export the "Datev DATA"
3. Column D, "Kurs," is incorrect

### Description of the issue/feature this PR addresses: 
**Issue:** DATEV documentation states that the column for "Kurs" should be the ratio of WKZ-Umsatz : WKZ-Basisumsatz, which is Foreign : Base Currency. Additionally, all sample files show this column's values being rounded to 6 decimal places. Currently, when Odoo exports the general ledger as DATEV data, there is no rounding of decimal places and the formula does base / foreign amount, `line_amount / line_amount_currency`.

**Solution:** In the `datev_export_csv.py` file, the relevant method is called `_l10n_de_datev_get_csv()`. In there, we can fix the line to round the value of `line_amount_currency / line_amount` to 6 decimal places.

### Current behavior before PR: 
Exporting the general ledger as DATEV data currently gives the reverse foreign currency rate and fails to round to 6 decimal places, which causes some values to be extremely long.

### Desired behavior after PR: 
The csv files should output the correct rate and be rounded appropriately.

### Steps to reproduce:

- In the settings enable: Multi-Steps Routes and rental transfers
- Unarchive the MTO route
- Create a rental product P with a buy route and a set vendor
- Create a rental order for 1 x P and set the the MTO route on the sol
- Confirm the order
#### > The delivery as well as the purchase for 1 unit of P was generated but the return was not.

### Cause of the issue:

The procurement generated to handle both the delivery and the return rental picking are handled by the `_create_procurements`: https://github.com/odoo/enterprise/blob/b0e48baaf99bdc4faefd2ffdd3bd5637fb548593/sale_stock_renting/models/sale_order_line.py#L353-L374 The `route_ids` set and used is the `mto_route` set on the sol: https://github.com/odoo/odoo/blob/0f061503e26ac8c441d62d91947419119e48c47a/addons/sale_stock/models/sale_order_line.py#L415-L422 https://github.com/odoo/odoo/blob/0f061503e26ac8c441d62d91947419119e48c47a/addons/sale_stock/models/sale_order_line.py#L282-L297
However, in the present case, the mto  route does not contain any rule with a relevant `location_src_id` in the rental location so that the return will not be generated.

Issue Before This Commit:
----------------------------------
In a single-company environment, the quality team email alias was created
without a company ID. As a result, incoming emails could not generate quality
tickets, making the email alias ineffective.

Steps to produce:
----------------------------------
- Install `quality_control` in a single-company environment.
- Create a quality team with a name and an email alias.
- Navigate to Settings → Technical → Aliases and check the newly created alias.
- The Company ID is False, preventing the creation of new tickets via email.

Cause
----------------------------------
In a single-company environment, the company_id field is not visible,
is not required, and has no default value, so it is never set.
The same issue can also occur in a multi-company environment when the user
explicitly creates a team without selecting a company.

After this Commit:
----------------------------------
The company_id is now set in the alias default values based on the quality
team’s company. It is also updated whenever the team’s company changes,
ensuring consistency and allowing incoming emails to reliably create quality
tickets in all environments.
