Hi,
I can confirm the problem. We have the same problem also in version 11.
Unbelievable nobody seen it before. But shouldn't apply your fix also when the location usage is 'customer', e.g. at returns ?

I think it is not enough to do is only in the _action_done. Because when you unlock the picking and edit the received quantity the wrong in_date is written back to the destination quant.

I think this is a very big problem and we should discuss that here because it leads that FIFO does not work correct.

Dear @AdriaGForgeFlow,

Thank you for your contribution but the version 12.0 is no longer supported.
We only support the last 3 stable versions so no longer accepts patches into this branch.

We apology if we could not look at your request in time.
If the contribution still makes sense for the upper version, please let us know and do not hesitate to recreate one for the recent versions. We will try to check it as soon as possible.
