A sales order containing a back-to-back item has been created.

The supply plan should have been run in Supply Chain Orchestration, not Planning Central.

Planning Central cannot create back-to-back supply, so the supply cannot be released.

Only Global Order Promising and Supply Chain Orchestration can be used to release and create new supplies for back-to-back orders.

The supply must first be created in Global Order Promising and then it can be released from Planning Central.
