  The SAP error message CNV20201323 typically relates to issues encountered during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is a discrepancy in the document number range during the migration process.
  Cause:

  Review Migration Settings:
  
  Check the settings in the migration tool you are using (e.g., SAP S/4HANA Migration Cockpit) to ensure that the document number ranges are correctly specified.
