We can not issue additional parts to a shortage by dragging the parts down to the kitting window even though the parts are in stock.

A.  Once inventory has been dragged from an inventory location, it can NOT be dragged again to fill shortages left from insufficient inventory on the first kit. The appropriate way to add more inventory to the kit from the same inventory location is to highlight the amount already kitted (in the lower right corner of the issue screen) and change the quantity to the revised quantity. That action will remove the additional quantity from inventory and place it in the work order.
