When a stock transfer (STW) has been created to move storage from one location (LOC) to another location (LOC), a supplier order (SPO) is created and automatically forwarded to a purchase order response (SOA)

to be used at the receiving location, which is waiting for the storage transfer. 

The goods have to be shipped from the stock location using standard picking and shipping processes.

When the goods arrive at the new location, the purchase order response (SOA) is transferred to a Goods reception (SSA).
