For planning production using only the production module without other modules such as production_work:
In production sometimes you will start with the Planned Start Date.
I know when will start the production. So I set the Planned Start Date.
Then I calculate manually how long the production will take, and I set the Planned Date.
But then I lose the Planned Start Date, as it is auto-completed with the value from the Planned Date.
I have read the opinion that @ced has regarding production planning in Tryton: it is better to use an external tool like Frepple.
Still I think some very simple planning can be done in Tryton, but right now it is very annoying to use the Planned Date and Planned Start Date because if I change one I lose the other.
As usual, for me personally I can override in a custom module this behavior, so I am not asking for help with this issue.
I would like to ask if there is any rationale for auto-completing the planned start date from the planned date.
If not then I would like to propose the following:
- Let the user change the Planned Date and Planned Start Date freely.
- Have a check that Planned start date is not after Planned Date.
- If either is left empty at saving, then autocomplete the missing value from the other.
If I get positive feed-back I would like to create the merge request implementing these changes myself.
PS: I know that there are more production modules such as production_work that may change the values of the production dates depending on work.
