• What is the cause and solution for SAP error message CNV_CMIS_M019 - Old and new mapping values must differ ?

  The SAP error message CNV_CMIS_M019 indicates that there is an issue with the mapping values in a conversion or migration process, specifically that the old and new mapping values must differ. This error typically arises during data migration or conversion activities, particularly when using the SAP Conversion Management Information System (CMIS) or similar tools.
  Cause:
  The error occurs when you attempt to map a value from the source system (old value) to a target system (new value) where both values are the same. This situation is not allowed because the mapping process requires a clear distinction between the old and new values to ensure that the data is transformed correctly.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Mapping Configuration: Check the mapping configuration in the migration tool. Ensure that the old and new values are indeed different. If they are the same, you need to change one of the values.
  
  
  Adjust Mapping Values: If the mapping is intended to change a value, modify the new value to reflect the desired transformation. For example, if you are migrating a status code from 'A' to 'A', change the new value to something else, like 'B' or 'C'.
  
  
  Check for Duplicates: Ensure that there are no duplicate mappings that could be causing confusion in the conversion process. Each mapping should be unique.
  
  
  Consult Documentation: Refer to the SAP documentation or migration guides related to the specific tool or process you are using. There may be specific guidelines or best practices for setting up mappings.
  
  
  Test the Changes: After making adjustments, run a test migration to ensure that the error is resolved and that the data is being mapped correctly.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific scenario.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context on mapping issues.
  Migration Tools: Familiarize yourself with the specific migration tools you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) as they may have unique features or requirements.
  Data Quality: Ensure that the data being migrated is of high quality and that any necessary data cleansing has been performed prior to migration.
  
  By following these steps, you should be able to resolve the CNV_CMIS_M019 error and successfully complete your data migration or conversion process.
