Once a pick has been posted to the NCAS, the items picked must be physically shipped to the consumer.

At times, a warehouse manager might ship more or less of an item than was picked. If an order must be completed with the quantity of an item shipped differing from the quantity of the item picked and posted, a shipping exception occurs. There are three types of shipping exceptions: overshipments, short shipments and partial shipments.

• An overshipment occurs when the quantity of an item shipped is greater than the quantity picked and posted for the order. An overshipment is considered complete.
• A short shipment occurs when the quantity of an item shipped is less than the quantity picked and posted for the order. A short shipment is also considered complete -- no more of the item will be shipped to the customer.
• A partial shipment occurs when the quantity of an item shipped is less than the quantity picked and posted for the order. A partial shipment, however, is not considered complete; the remaining items will be shipped at a later time.
