• What is the cause and solution for SAP error message CNV20201325 - No relevant external number ranges ?

  The SAP error message CNV20201325: No relevant external number ranges typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the system is unable to find any external number ranges that are relevant for the operation being performed.
  Cause:
  
  Missing Number Ranges: The external number ranges that are required for the migration process have not been defined in the system.
  Configuration Issues: The configuration settings for number ranges may not be correctly set up or may not match the requirements of the migration process.
  Data Mapping Issues: The mapping of data from the source system to the target system may not have been properly defined, leading to the system not recognizing the external number ranges.
  Authorization Issues: The user executing the migration may not have the necessary authorizations to access the number range objects.
  
  Solution:
  
  
  Define External Number Ranges:
  
  Go to the transaction code SNRO (Number Range Objects) and check if the relevant number range objects are defined.
  If they are not defined, create the necessary external number ranges for the relevant objects.
  
  
  
  Check Configuration:
  
  Ensure that the configuration for the number ranges is correctly set up in the system. This may involve checking the customizing settings in the relevant modules (e.g., FI, MM, SD).
  Use transaction SPRO to navigate to the relevant configuration areas and verify the settings.
  
  
  
  Review Data Mapping:
  
  Check the data mapping settings in the migration tool to ensure that the external number ranges are correctly mapped to the corresponding internal number ranges in the target system.
  
  
  
  User Authorizations:
  
  Verify that the user executing the migration has the necessary authorizations to access and modify the number range objects. This may involve checking roles and authorizations in transaction PFCG.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation related to the specific migration process you are using. There may be specific steps or prerequisites that need to be followed.
  
  
  
  Check SAP Notes:
