The quantity on hand (QOH) of an inventory part no longer calculates after it has been used in the Bill of Materials of an Inventory Assembly Item.
One or more of the line items in the Bills of Materials (the list of items that compose the Inventory Assembly) were left blank (not removed) while editing the Inventory Assembly Item.
This causes the Inventory Part following the blank item to stop calculating the quantity on hand.
Correct the problem by removing the blank line from the Bills of Materials, and then reset any Build Assembly Item the problem Inventory Part has been used in.
