• What is the cause and solution for SAP error message KI851 - Report has already been started by user & ?

  The SAP error message KI851, which states "Report has already been started by user &," typically occurs when a user attempts to execute a report that is already running in the background or has been initiated by the same user. This is a common issue in SAP systems, especially when dealing with long-running reports or batch jobs.
  Cause:
  
  Concurrent Execution: The user is trying to run the same report multiple times simultaneously.
  Background Job: The report may have been started in the background, and the system does not allow the same report to be executed again until the first instance is completed.
  Session Management: The user may have multiple sessions open, and the report is already running in one of those sessions.
  
  Solution:
  
  
  Check Background Jobs:
  
  Go to transaction code SM37 (Job Monitoring) to check if the report is running in the background.
  If you find the job, you can either wait for it to complete or cancel it if it is stuck.
  
  
  
  Check Active Sessions:
  
  Use transaction code AL08 to see if the report is running in another session for the same user.
  If you find it running, you can either wait for it to finish or log off from that session.
  
  
  
  Wait for Completion:
  
  If the report is running and you do not want to cancel it, simply wait for it to complete before trying to run it again.
  
  
  
  Use Different Parameters:
  
  If you need to run the report with different parameters, consider modifying the selection criteria to avoid the conflict.
  
  
  
  Contact SAP Basis Team:
