Post document with zero quantity

You can post a warehouse shipment/receipt or register a pick document with zero quantity when underdelivery is enabled and Allowed Underdelivery % is set to 100.

When you post a warehouse shipment/receipt or register a pick with zero quantity and enable underdelivery and there is only one shipment/receipt/pick line, the system deletes the document. When multiple warehouse shipment/receipt/pick lines exist, the system deletes the line(s) with zero quantity. The outstanding quantity is automatically set to zero on successful posting.
