Smart SAP Assistant

• What is the cause and solution for SAP error message /PM0/ALB_FND_MSG653 - Conversion has already been scheduled ?

  The SAP error message /PM0/ALB_FND_MSG653: Conversion has already been scheduled typically occurs in the context of data conversion processes, particularly when dealing with the Advanced Business Application Programming (ABAP) or when using specific SAP modules that involve data migration or conversion tasks.
  Cause:
  This error indicates that a conversion process has already been initiated for the specified data set or object. The system prevents multiple conversion processes from being scheduled simultaneously to avoid conflicts or data integrity issues. This can happen if:
  
  A previous conversion job is still running or has not been completed.
  There was an attempt to schedule a conversion job for the same object or data set while another job is already in progress.
  The system did not properly clear the status of a previous conversion job, leading to confusion in job scheduling.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Running Jobs: 
  
  Go to transaction code SM37 (Job Monitoring) to check if there are any active jobs related to the conversion process. Look for jobs that are in the status of "Running" or "Released."
  
  
  
  Monitor Job Status:
  
  If you find a job that is still running, you may need to wait for it to complete. If it is stuck or taking too long, you may need to cancel it.
  
  
  
  Cancel Stuck Jobs:
  
  If you determine that a job is stuck, you can cancel it from the SM37 transaction. Select the job and choose the option to cancel it.
  
  
  
  Check Job Logs:
  
  Review the job logs for any errors or issues that may have caused the job to hang or not complete successfully.
  
  
  
  Re-schedule the Conversion:
  
  Once you have confirmed that no other conversion jobs are running, you can attempt to schedule the conversion process again.
  
  
  
  System Restart:
  
  In some cases, if the issue persists and you suspect a system-level issue, a restart of the application server may be necessary. However, this should be done with caution and typically requires coordination with your Basis team.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific conversion process you are working with for any additional troubleshooting steps or known issues.
  
  
  
  Contact SAP Support:
  
  If the problem continues and you cannot identify the cause, consider reaching out to SAP support for further assistance.
