@rafael : @tc and I just discussed this. I think you made this local change (maybe it was not you) to be able to enter an inventory of computer immobilisations. In my understanding, setting the items on an inventory line should be enough to know the quantity (using the same Movement_isQuantityEditable logic that in other trade movements) and user should not have to change quantity.

Jerome, you are right, this change can be reverted so.
