• What is the cause and solution for SAP error message CNV_PE_UI826 - Value for simulation and writing data must not contain same value ?

  The SAP error message CNV_PE_UI826 indicates that there is a conflict in the values being used for simulation and writing data during a data migration or conversion process. Specifically, it suggests that the same value is being used for both simulation and actual data writing, which is not allowed in the context of the operation being performed.
  Cause:
  
  Data Overlap: The error typically arises when the same value is assigned to both the simulation and the actual data writing fields. This can happen if the configuration or mapping of the data is incorrect.
  Configuration Issues: There may be a misconfiguration in the data migration tool or the settings that dictate how data should be processed.
  Incorrect Mapping: The mapping of source data to target fields may not be set up correctly, leading to the same value being used in both contexts.
  
  Solution:
  
  Review Configuration: Check the configuration settings of the data migration tool you are using. Ensure that the simulation and writing data values are distinct and correctly set up.
  Adjust Mapping: Go through the mapping of your data fields. Make sure that the values assigned for simulation and writing are not the same. You may need to create different mappings or adjust the logic to ensure they are unique.
  Test with Different Values: If possible, run a test with different values for simulation and writing to see if the error persists. This can help isolate the issue.
  Consult Documentation: Refer to the SAP documentation or help resources related to the specific data migration tool you are using. There may be specific guidelines or best practices that can help resolve the issue.
  Seek Support: If the issue persists after checking the above points, consider reaching out to SAP support or your internal SAP team for further assistance. They may have encountered similar issues and can provide insights or solutions.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Data Migration Tools: Familiarize yourself with the specific data migration tools being used (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) as they may have unique configurations and requirements.
  Testing Environment: Always perform tests in a non-production environment to avoid impacting live data during troubleshooting.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
