#COE KKS01 SAP S/4HANA Public Cloud Good Receipt error from Subcontractor

Hi,

We send goods from WM Warehouse with ''Outbound Delivery Document'' to the Subcontractor, then we get this error when we want to goods from Subcontractor, back to the WM Warehouse with ''Inbound Delivery Document''. What is the reason this error and how to fix it?

Error: "Goods receipt for inbound delivery is not allowed in AD Subcontracting"

If you have any idea/suggestion please let me know. Thank you.
