Smart SAP Assistant

• What is the cause and solution for SAP error message CNV_PE_POST842 - Batch job &1 (&2) is already registered in CNV_PE_BTC_JOBS ?

  The SAP error message CNV_PE_POST842 indicates that a batch job is already registered in the table CNV_PE_BTC_JOBS. This typically occurs during data migration or conversion processes, particularly when using SAP's Conversion Tools (like the SAP S/4HANA Migration Cockpit or other data migration tools).
  Cause:
  The error arises when:
  
  A batch job with the same name or identifier is already running or has been registered in the system.
  There may be a failure in the previous job that left an entry in the job table, preventing new jobs from being registered with the same identifier.
  There could be a misconfiguration or a duplicate submission of the same job.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check Existing Jobs:
  
  Use transaction code SM37 to check the status of the batch jobs. Look for jobs with the same name or identifier that might still be running or have failed.
  If you find a job that is still running, you may need to wait for it to complete or terminate it if it is stuck.
  
  
  
  Delete or Update Job Entry:
  
  If the job has failed or is no longer needed, you can delete the entry from the CNV_PE_BTC_JOBS table. This can be done using transaction SE16N or SE11 to access the table and remove the specific entry.
  Be cautious when deleting entries directly from the database; ensure that you have backups and that you understand the implications.
  
  
  
  Re-run the Job:
  
  After resolving the issue with the existing job, you can attempt to re-run the batch job that was previously failing.
  
  
  
  Check for Duplicates:
  
  Ensure that your process or script does not inadvertently submit the same job multiple times. Implement checks to prevent duplicate submissions.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation related to the specific migration or conversion tool you are using for any additional troubleshooting steps or best practices.
  
  
  
  Contact SAP Support:
  
  If the issue persists and you are unable to resolve it, consider reaching out to SAP Support for further assistance.
