• What is the cause and solution for SAP error message CNV20200479 - Numberrange overflow when calculating Balance Sheet Adjustment Runs ?

  The SAP error message CNV20200479, which indicates a "Number range overflow when calculating Balance Sheet Adjustment Runs," typically occurs during the execution of a financial adjustment process in SAP, particularly in the context of data migration or financial closing activities. This error is related to the number range management in SAP, where the system attempts to assign a number that exceeds the defined range for a particular object.
  Cause:
  
  
  Number Range Exhaustion: The most common cause of this error is that the number range defined for the relevant object (e.g., document numbers, transaction numbers) has been exhausted. This can happen if the system has processed a large number of transactions and has reached the upper limit of the defined number range.
  
  
  Configuration Issues: Incorrect configuration of number ranges in the system can also lead to this error. If the number range intervals are not set up properly, it may lead to conflicts or exhaustion.
  
  
  Data Migration Issues: If you are performing data migration (e.g., using SAP S/4HANA Migration Cockpit or other tools), the migration process may attempt to create or adjust records that exceed the available number range.
  
  
  Solution:
  
  
  Check Number Range Settings:
  
  Go to transaction code SNRO (Number Range Objects) and check the number range object related to the error.
  Verify the current status of the number range and see if it has been exhausted.
  
  
  
  Extend Number Range:
  
  If the number range is exhausted, you can extend it. This can be done by:
  
  Going to transaction code SNRO.
  Selecting the relevant number range object.
  Adjusting the intervals to increase the upper limit.
  
  
  
  
  
  Review Configuration:
  
  Ensure that the configuration for number ranges is correct and that there are no overlaps or gaps in the defined ranges.
  
  
  
  Data Migration Adjustments:
  
  If the error occurs during data migration, review the migration settings and ensure that the number ranges are properly defined for the objects being migrated.
