[FUNCIONTAL REVIEW] [NEED TO CHECK]

1. Test to split some analytic item (OK)
   

2. It could be better with the amount field
   

3. The child_ids table is duplicated, maybe it's an effect if install other module: (account_analytic_wip). If the modules use same field it could be a problem in the future?
   
   This field is created in analytic_activity_based_cost module on:
   

   account-analytic/analytic_activity_based_cost/models/account_analytic_line.py

   Line 19 in 924b249

   child_ids = fields.One2many(

   
   I guess this module must to be included on dependency in manifest.py, is it make sense?

This tree view is added with analytic activity based cost

3. I guess this module must to be included on dependency in manifest.py, is it make sense?

This module is in Alpha, when I tried to depend on it this error was triggered

account_analytic_line_split (Beta) depends on analytic_activity_based_cost (Alpha)

And I think it doesn't make much sense to depend on this module because the purposes of the modules are different, I change the name of the fields to parent_line_id and child_line_ids, and in the view, I control the visibility of the fields only displaying them when they are filled in

I also added unit tests, this pull request is ready for review now

[WesleyOliveira98]

To review this pull request, you must uninstall account_analytic_no_lines because this module disables the generation of an analytic line from a move line
