Process a transfer order

Users fulfill transfer orders by creating shipments in the source warehouse that are received later at the destination warehouse.

If you need to process one transfer order or a few transfer orders, you can do this by using the Sales orders (SO301000) window.
You can also process multiple transfer orders by using the Process orders (SO501000)window.
If you need to process a multi-line transfer order that involves multiple warehouses (and hence generates multiple shipments), you should also use the Process orders (SO501000) window.
