User was not able to create the Return Purchase Order Outbound Delivery when using VL10B or VL10D
Solution:
During the MRP availability checks, SAP consider the stocks even though it was at a different storage location. As long as another delivery date is earlier than your return purchase order delivery, then MRP checks will not allowed you to create your return po delivery.
Once I asked the user to delete the first delivery order that was reserving the stocks, the Return Purchase Order Outbound Delivery was created successfully.
