The SAP error message CNV_CDMC_CA147 indicates that no objects were found in the customer namespace in the specified system. This error typically arises during data migration or conversion processes, particularly when using the SAP Customer Data Migration Cockpit (CDMC) or similar tools.
Cause: No Custom Objects: The most straightforward cause is that there are indeed no custom objects created in the customer namespace (usually denoted by a namespace starting with "Z" or "Y"). Incorrect Configuration: The system might not be correctly configured to recognize the customer namespace, or the relevant transport requests may not have been imported. Authorization Issues: The user executing the migration might not have the necessary authorizations to view or access objects in the customer namespace. System Issues: There could be issues with the system itself, such as inconsistencies in the database or problems with the transport layer.
Solution: Verify Custom Objects: Check if there are any custom objects created in the customer namespace.
