• What is the cause and solution for SAP error message B1679 - Conversion can only be started after the test run ?

  The SAP error message B1679, which states "Conversion can only be started after the test run," typically occurs during the data conversion process in SAP, particularly when using tools like the SAP Data Migration Workbench or during a system upgrade or migration.
  Cause:
  This error indicates that the system is trying to initiate a conversion process without having completed a necessary test run first. The test run is a preliminary step that allows you to validate the conversion process without making any actual changes to the data. If the test run has not been executed or completed successfully, the system will not allow the actual conversion to proceed.
  Solution:
  To resolve this error, follow these steps:
  
  
  Perform a Test Run: 
  
  Ensure that you have executed the test run for the conversion process. This is usually done in the same transaction or program where the conversion is initiated.
  Check the logs and results of the test run to ensure there are no errors or issues that need to be addressed.
  
  
  
  Review Test Run Results: 
  
  If the test run completed with warnings or errors, address those issues before attempting the actual conversion. This may involve correcting data inconsistencies or configuration issues.
  
  
  
  Re-run the Test: 
  
  If necessary, re-run the test to confirm that all issues have been resolved.
  
  
  
  Start the Conversion: 
  
  Once the test run is successful, you can proceed with the actual conversion process.
  
  
  
  Check Authorization: 
  
  Ensure that you have the necessary authorizations to perform both the test run and the actual conversion.
