  The SAP error message CNV_DMC_MC_EXCEPTION145: There are no entries to be deleted typically occurs during data migration or conversion processes, particularly when using the SAP Data Migration Cockpit (DMC) or similar tools. This error indicates that the system attempted to delete entries from a table or dataset, but there were no entries available to delete.
