2909027 - Subcontracting components cannot be added in Purchase Order

When attempting to add new Subcontracting components in a Purchase Order, the user is unable to do so because the “Add Detail Entry” button is not available in the Change Purchase Order – Advanced app or the create icon is missing in the Manage Purchase Order app. 

SAP S/4HANA Cloud Public Edition

The Purchase Order already has a good receipt in the Purchase Order History Tab.

This is the correct behavior (works as designed). Changing or adding components after a GR posting would lead to inconsistencies. This would affect all further GRs. That's why it is not possible to change/delete or add components after the first GR.

This is the standard system behavior
