• What is the cause and solution for SAP error message CNV_DMC_WDA069 - Cannot start transfer; there is no unprocessed data in root table &1 ?

  The SAP error message CNV_DMC_WDA069 indicates that the system is unable to start a data transfer because there is no unprocessed data available in the specified root table. This error typically occurs during data migration processes, particularly when using the SAP Data Migration Cockpit or similar tools.
  Cause:
  
  
  No Unprocessed Data: The primary cause of this error is that the root table specified in the error message does not contain any records that are marked as unprocessed. This could happen if:
  
  The data has already been processed in a previous migration run.
  The data was deleted or not loaded correctly into the root table.
  The selection criteria used to identify unprocessed data are too restrictive.
  
  
  
  Incorrect Configuration: There may be an issue with the configuration of the data migration process, such as incorrect mapping or settings that prevent data from being recognized as unprocessed.
  
  
  Data Load Issues: If there were issues during the data load process (e.g., errors, interruptions), it could result in the root table not having any unprocessed records.
  
  
  Solution:
  
  
  Check Data in Root Table: Verify the contents of the root table specified in the error message. Ensure that there are records present and that they are marked as unprocessed. You can do this by executing a SQL query or using transaction codes like SE11 or SE16.
  
  
  Review Migration Logs: Check the logs of the data migration process to identify any errors or warnings that may indicate why data is not being processed. Look for any messages related to data loading or processing.
  
  
  Adjust Selection Criteria: If applicable, review and adjust the selection criteria used for identifying unprocessed data. Ensure that the criteria are not too restrictive and that they correctly identify the records you want to process.
  
  
  Re-load Data: If you find that the data is missing or was not loaded correctly, you may need to re-load the data into the root table. Ensure that the data load process completes successfully without errors.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific data migration tool you are using. There may be additional troubleshooting steps or configuration settings that need to be reviewed.
  
  
  Contact SAP Support: If the issue persists after checking the above points, consider reaching out to SAP support for further assistance. They may provide insights specific to your system configuration or version.
  
  
  Related Information:

  Data Migration Cockpit: If you are using the SAP Data Migration Cockpit, review the specific guidelines and best practices for data migration to ensure that you are following the correct procedures.
