Under Material Control, Transfers, there are 2 tabs on that screen: "Finished Parts to Inventory" and "Job Materials to Inventory". The use of the word 'inventory' is too ambiguous. It means 2 different things on each of those tabs.
Recommend changing the tabs to read:
"Work In Process to Finished Goods"
and
"Excess WIP back to Raw Matl, Hardware, Supplies"
