Code review comment for lp:~akretion-team/stock-logistic-flows/70-product_serial-plus-plus

@Lionel

I agree with you ; my merge proposal is a first step in this direction, with the introduction of :
- product_serial_sale_stock
- product_serial_purchase

but I won't do the split you talk about in this merge proposal, because it's out of the scope of this MP. It would have to be done in a new MP dedicated to this task.
