must be located and picked from the warehouse shelves. It also provides formal authorization for warehouse personnel to release the specified items. After picking the stock, the order is verified for accuracy and the goods and verified stock release document are sent to the ship goods task. If inventory levels are insufficient to fill the order, a warehouse employee adjusts the verified stock release to reflect the amount actually going to the customer. The employee then prepares a back-order record, which stays on file until the inventories arrive from the supplier (not shown in Figure 4-1). Back-ordered items are shipped before new sales are processed.
