  The SAP error message CNV20201307 typically relates to issues with external number ranges in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the specified external number range for a particular sub-object has exceeded its maximum limit.
  Cause:
  
  Exceeded Number Range: The error occurs when the system attempts to assign a number from an external number range that has already reached its maximum limit. This can happen if the number range is not properly configured or if the migration process is trying to create more entries than the defined maximum allows.
  Configuration Issues: The external number range may not be set up correctly in the system, or the number range object may not be properly defined for the specific sub-object.
  Data Migration Issues: During data migration, if the data being migrated exceeds the defined limits of the number range, this error can occur.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) and check the configuration for the relevant number range object.
  Ensure that the number range is defined correctly and that the maximum number is set appropriately to accommodate the expected data volume.
  
  
  
  Adjust Number Range:
  
  If the maximum number is too low, you can extend the number range by adjusting the settings in the number range object. This may involve increasing the upper limit or creating a new number range that can accommodate more entries.
  
  
  
  Review Migration Data:
  
  Check the data being migrated to ensure that it does not exceed the limits of the number range. If necessary, adjust the data or the migration strategy to fit within the defined limits.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific migration process you are using. There may be specific guidelines or recommendations for handling number ranges during migration.
  
  
  
  Contact SAP Support:
