• What is the cause and solution for SAP error message KI873 - Program has already been started ?

  The SAP error message KI873 ("Program has already been started") typically occurs when a user attempts to execute a program or transaction that is already running in the background or has been initiated previously. This can happen in various scenarios, such as when a user tries to run a report or transaction that is already being processed.
  Causes:
  
  Duplicate Execution: The user may have inadvertently started the same program or transaction multiple times.
  Background Job: The program might be running as a background job, and the system does not allow the same job to be executed again until the first instance is completed.
  Session Management: There may be issues with session management, where the system does not recognize that the previous instance has completed.
  Locking Mechanism: SAP uses locking mechanisms to prevent data inconsistencies, and if a program is already locked by another session, it cannot be started again.
  
  Solutions:
  
  Check Background Jobs: Go to transaction code SM37 to check if the program is running as a background job. If it is, you can wait for it to complete or cancel it if necessary.
  Review Active Sessions: Use transaction code SM04 to see if there are multiple sessions open for the same user. If so, you may need to log off from the other sessions.
  Wait for Completion: If the program is running, simply wait for it to finish before attempting to run it again.
  Transaction Monitoring: If you are an administrator, you can monitor the transaction using SM50 or SM66 to see if the program is stuck or taking too long to execute.
  Check for Locks: Use transaction code SM12 to check for any locks that might be preventing the program from running. If you find any locks that are no longer needed, you can delete them.
  Restart the Program: If you believe the previous instance has completed but the system is still showing the error, you may need to restart the SAP GUI or log out and log back in.

  User Permissions: Ensure that the user has the necessary permissions to execute the program, as permission issues can sometimes lead to unexpected behavior.
