Scenario: Create a service to "Procure and Install" a piece of equipment at a customer address. I created the service order, added the item no (not the service item yet) which allows me to see the demand in the order planning screen. I then create the PO from that screen. I want to drop-ship the item to the customer site and invoice everything on the service order.
On the PO header, I changed the Ship-To to "Customer Address". I received warning below regarding changing the address on the lines manually. However, I cannot find where I can select the customer's address.

How is this accomplished?
