Outsource Operation & Drop Shipment

We order base fabrics from Vendor A and ship directly to Vendor B to dye. The PO to Vendor B is generated and the job for outsource processing is generated. We pay for Vendor B’s invoice when the fabrics are dyed, not when they are shipped. So the PO to Vendor B that was generated has already been closed and paid. We just received two orders from Customer A that will ship directly from Vendor B.

Is there a way to process this drop shipment to Customer A?
