Trying to get the PO number for a subcontractor to print on the packing slip when we resupply them.  Right now the source document to resupply subcontractor is the expected incoming shipment of the completed parts which makes sense for pull route.

This information is very critical for my subcontractor to keep our orders straight.  We can have thousands of parts and dozens of orders waiting for resupply as we manufacture the product to be resupplied.
