## Issue
In the Planning app, users within the *Planning / User* groups could not take open shifts. The button *"I Take It"* would not be displayed when clicking on the shift.

## Steps to reproduce
1. Install the *Planning* (`planning`) app
2. In the Planning app, as an admin, create and publish an open shift
3. Log in as a *User*, open the *Planning* app, and click on the open shift
4. **The _"I Take It"_ button is not displayed**

When logging in as a user who is **not** part of the *Planning / User* group, the *I Take It* button is displayed.

## Cause

The condition for the *I Take It* button to be displayed is the following:

https://github.com/odoo/enterprise/blob/301e3c40c3272a6ae89a1eb4387d7d244e1dc52c/planning/views/planning_views.xml#L282-L283

The condition that makes the button invisible is `not context.get('my_planning_action')`. When the user is part of *Planning / User*, the schedule they see when opening the *Planning* app is the *"Schedule by Resource"*, which has the following context:

https://github.com/odoo/enterprise/blob/301e3c40c3272a6ae89a1eb4387d7d244e1dc52c/planning/views/planning_views.xml#L716

When a user who **is not** part of the *Plannig / User* group opens the *Planning* app, they see their own schedule, where the context is different than in the first case:

https://github.com/odoo/enterprise/blob/301e3c40c3272a6ae89a1eb4387d7d244e1dc52c/planning/views/planning_views.xml#L636

Because the `my_planning_action` property is in the context (and all the other conditions are respected), the button is displayed.

#### Issues:
VAT Book should download for all selected companies with same CUIT as the current one.

#### Step to reproduce:
- In a company in Argentina ("Parent Company")
- Create a branch "Child Company A" with no CUID
- Create a branch "Child Company B" with a different CUID than parent
- Go to "Child Company A"
- Either:
  - i.  Select both "Parent Company" and "Child Company A" but not "Child Company B"
  - ii. Select all 3 "Parent Company", "Child Company A" and "Child Company B"
- In Accounting > Report > Tax Return :
- Download the VAT Book (wheel > "VAT book(ZIP)")

#### Current behavior:
i.  Get Invalid Operation
ii. Download the VAT Book for "Parent Company" only

#### Expected behavior:
- Download the VAT Book for both "Parent Company" and "Child Company A"

A previous call to get_options provide the client with the info about which selected companies have the same CUIT as the current company. Therefore companies in the options are the correct ones.
