On a sale with a product kit when I make an amendment modifying the quantity of the kit sold, this is not reflected in the quantity of the components on delivery.
Do you have the same behavior?
It should work if the kit is of type kit because the shipments should be recreated.
Not sure if it works on the kits of type goods.
Which type of kit are you using?
In my question I had tested on a kit of type ‘kit’ and it does not work on my base, but on a kit of type ‘good’ it works well (the delivery is well updated).
Indeed the stock moves from the components are not deleted so they are not recreated: Issue 11355: Amendment does not clear stock moves from components - Tryton issue tracker
