The system asks the user for a serial number during material picking for a Sale Order (or Internal Sale Order) if the item is serial tagging enabled.

When serial tagging is enabled for sales order pick, the corresponding Return Material Authorization (RMA) transaction will also be serial controlled. Whether same serial numbers are received as were shipped in the original shipment are dependent on the setting of Validate Serial Numbers at RMA Receipt in the Receiving Parameters window.

When the item is received during an RMA transaction, it does not have the serial association anymore with the received quantity. The on hand balance increases by the received quantity and the serial status is Defined but not Used.

The Receiving Open Interface validates the serial numbers if the item is serial tagging enabled at Sales Order Pick.
