Outside Processing Work order shipment not generated and shows PO Approved as zero

Summary:

We are stuck with an outside processing Work Order in which the supplier operation is not showing the shipment. There is no shipment line generated as well and upon further investigation we found that the PO Approved quantity is showing as zero on the Review Supplier Operations details page.

The PO is approved and even received into inventory which is reflecting as Over Receipt quantity on the Supplier Operation details. What could be the possible reason for the Shipment line to not be generated.
