• What is the cause and solution for SAP error message CNV20308025 - Comparison has already been confirmed; can only be displayed ?

  The SAP error message CNV20308025 indicates that a comparison in a data migration or conversion process has already been confirmed, and therefore, it can only be displayed but not modified or re-confirmed. This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion scenarios.
  Cause:
  
  Previous Confirmation: The primary cause of this error is that the comparison process has already been confirmed in a previous step. Once a comparison is confirmed, it is locked to prevent further changes to ensure data integrity.
  Data Migration Process: This error often occurs during the data migration process where data is being compared between source and target systems, and the user attempts to re-confirm a comparison that has already been finalized.
  
  Solution:
  
  View the Comparison: Since the comparison has already been confirmed, you can only view the results. Navigate to the relevant transaction or report to see the details of the confirmed comparison.
  Check for Previous Steps: Review the previous steps in the migration process to ensure that the comparison was indeed confirmed. If you need to make changes, you may need to revert to an earlier state if possible.
  Re-run the Comparison: If you need to perform a new comparison, you may need to reset the process or create a new comparison scenario, depending on the specific tool or transaction you are using.
  Consult Documentation: Refer to the SAP documentation or help resources related to the specific migration tool you are using for more detailed instructions on how to handle confirmed comparisons.
