Non-stocked or manufactured non-stock items generate a unique item when placed on an order or purchase order. When an item has been generated in this fashion, the type is modified to "renumbered." Users cannot designate an item as "renumbered" manually. Non-stocked items remain a "renumbered" type until they are sold. After sale, the type on the renumbered item is modified to "resale." This is done because, after being sold, an assumption is made that any further activity for the specific non-stocked renumbered item would be limited to a return. Renumbered items may not be sold unless linked with a customer order.
