Manually create a returns order in the ordering system.
The returns order creates an unchecked delivery in the supplying system.
You must then manually convert the unchecked delivery into a delivery.
The system then posts the goods receipt into the unrestricted-use stock or into the returns blocked stock. As soon as the goods have been posted into the unrestricted-use stock, the system reports this to the SAP APO system.
The credit memo is created in the ordering system with reference to the returns order. For cross-company-code deliveries, you must create the internal credit memo manually.
