  The SAP error message SERVICES_CMS041 indicates that there are duplicate values for the CAG (Customer Account Group) External ID in the system. This typically occurs in scenarios where the system expects unique identifiers for certain entities, and duplicates can lead to inconsistencies or errors in processing.
