  The SAP error message CNV_20000235 typically occurs during the data migration process, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is an issue with the number of accounting documents that need to be renamed using an external number range.
  Cause:
  
  External Number Range Configuration: The error may arise if the external number range for accounting documents is not properly configured in the system. This can happen if the number range is not defined or if it is not active.
  Exceeding Limits: The number of accounting documents that need to be renamed may exceed the limits set in the external number range configuration.
  Data Migration Settings: Incorrect settings in the data migration process can lead to this error, especially if the mapping of document numbers is not correctly defined.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) and check the configuration for the relevant number range object (e.g., FBNR for financial documents).
  Ensure that the external number range is defined, active, and has sufficient intervals to accommodate the number of documents being processed.
  
  
  
  Adjust Number Range Intervals:
  
  If the number of documents exceeds the current intervals, you may need to extend the number range intervals to accommodate the additional documents.
  You can do this by editing the number range intervals in the same SNRO transaction.
  
  
  
  Review Migration Settings:
  
  Check the settings in the migration tool you are using. Ensure that the mapping of document numbers is correctly set up and that the external number range is being referenced properly.
  If necessary, consult the migration documentation for specific instructions related to your migration scenario.
  
  
  
  Test Migration:
  
  After making the necessary adjustments, perform a test migration to see if the error persists. Monitor the logs for any additional errors or warnings.
