• The SAP error message CNV_MBT_46302 typically indicates that there is an attempt to save data that has already been saved in the system. This error is often encountered during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools.

  Check for Duplicates: Before running the migration again, check the target system for existing records
