Symptom
Error Message KD 325 occurred when saving Settlement Rule saying ‘Settlement within project hierarchy is not possible’
Environment
SAP S/4HANA Cloud
Cause
The sender cannot be settled to the receiver because both WBS elements are within the same project hierarchy, which is not supported.
Resolution
Change the settlement rule to a different receiver.
If you want to settle project with hierarchy, you can choose to use the option "Pass-Down Settlement Rule".
