• What is the cause and solution for SAP error message MPD191 - Maintenance plan was started, but a batch job is in process ?

  The SAP error message MPD191 indicates that a maintenance plan was initiated, but there is already a batch job running that is preventing the new maintenance plan from executing. This situation typically arises in the context of SAP Plant Maintenance (PM) when multiple maintenance plans or jobs are scheduled to run concurrently.
  Cause:
  
  Concurrent Jobs: The most common cause is that another maintenance plan or job is currently being processed in the background, which locks the resources needed for the new maintenance plan to start.
  System Configuration: There may be system settings or configurations that limit the number of concurrent jobs that can run, leading to this error when the limit is reached.
  Job Scheduling Conflicts: If jobs are scheduled to run at the same time, they may conflict with each other, causing one to be blocked.
  
  Solution:
  
  Check Background Jobs: Use transaction code SM37 to check the status of background jobs. Look for any jobs that are currently running and may be related to the maintenance plan.
  Wait for Completion: If you find that a job is running, you may need to wait for it to complete before starting the maintenance plan again.
  Adjust Scheduling: If the issue is recurring, consider adjusting the scheduling of maintenance plans or jobs to avoid conflicts. This can be done by staggering the start times of jobs.
  Increase Concurrent Job Limit: If your system allows it, you may want to increase the limit on concurrent jobs. This typically requires configuration changes and should be done in consultation with your SAP Basis team.
  Manual Intervention: If necessary, you can manually terminate the running job if it is safe to do so. This can be done in transaction SM37 by selecting the job and choosing to cancel it.
