This typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when you are trying to define a mapping for a message type or class that has already been defined.
Cause:

- Incorrect Configuration: There may be a misconfiguration in the mapping settings or the way the mapping is being called.

Delete Unused Mappings:
