Describe the bug

Analytic items created from a project_task_stock cannot be grouped by task

To Reproduce

Affected versions: 18.0 (others not tried)

Steps to reproduce the behavior:

1. Install project_task_stock (project_stock) on a fresh instance
2. Configure according to module instructions
3. Create project with task in stage that allows Stock pickings (Stock info tab)
4. Add products to task and confirm/transfer them (have to have cost > 0)
5. Accounting/Acconting/Analytic Items
   Analytic items list shows.
   Try to group by task!

Analytic items created on the task through timesheet tab group correctly by task

Expected behavior
A clear and concise description of what you expected to happen.

Analytic items should be able to group by task if they were created from a task.

The behavior described is correct; it is specifically intended that the project https://github.com/OCA/project/pull/1048 not be defined in order to avoid inconsistencies. If you want to analyze something, you should use the stock_task_id field.

I did not check it for a while. Is stock_task_id added to analytics?

From what I saw back then, it was not possible to analyze by anything related to task identification.

@victoralmau , from what I see in the pull request you linked, one can conclude that analytics per project or task is not allowed.
I did not dig deeper but that does not make business sense.

Can you explain this PR further?
