When you use assembly orders and reserve items the total available quantity is calculated wrong.

Eg. We have added item5 pcs of item AAA to an assembly order and reserved the item in stock. We have 10 pcs in stock of the item. We pick the items on the assembly order and afterwards we create an salesorder for 3 pcs of AAA, but we are not able to reserve the items because the assembly order both reserve 5 pcs. and allocates 5 pcs, total 10 pcs. This means that we have to go back to the assembly order and remove the reservations after the items have been picked, so that we can reserve the quantity on the salesorder.
