• What is the cause and solution for SAP error message CNV20201417 - Overlap of number ranges for &1, target subobj. &2,to-year &3: ?

  The SAP error message CNV20201417 indicates that there is an overlap in number ranges for a specific object during a data migration or conversion process. This typically occurs when the system is trying to assign a number range to a target object that conflicts with an existing number range.
  Cause:
  
  Overlapping Number Ranges: The error arises when the number ranges defined for the source and target objects overlap. This can happen if the same number range is being used for different objects or if the ranges are not properly defined.
  Configuration Issues: Incorrect configuration of number ranges in the target system can lead to this error. This may include missing or incorrectly defined number ranges for the target sub-object.
  Data Migration Process: During data migration, if the source data contains values that fall within the number range of the target object, it can trigger this error.
  
  Solution:
  
  Check Number Ranges: Review the number ranges defined for both the source and target objects. Ensure that there are no overlaps. You can do this by navigating to the number range configuration in the SAP system (Transaction code: SNRO).
  Adjust Number Ranges: If overlaps are found, adjust the number ranges to ensure they are distinct. This may involve creating new number ranges or modifying existing ones.
  Data Mapping: Ensure that the data mapping between the source and target objects is correctly defined. This includes verifying that the values being migrated do not conflict with existing values in the target system.
  Test Migration: After making adjustments, perform a test migration to ensure that the error does not occur again. Monitor the logs for any further issues.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration process you are using, as there may be additional guidelines or best practices.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SNRO (Number Range Objects) to manage number ranges and check for overlaps.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Migration Tools: If you are using a specific migration tool (like SAP S/4HANA Migration Cockpit), consult the documentation for that tool for any specific configurations or settings related to number ranges.
  
  By following these steps, you should be able to resolve the CNV20201417 error and successfully complete your data migration or conversion process.
