• What is the cause and solution for SAP error message CH137 - Application & (&) already running ?

  The SAP error message CH137 indicates that an application or process is already running, which prevents the initiation of a new instance of that application. This can occur in various scenarios, such as when trying to start a background job, a report, or a transaction that is already being executed.
  Causes:
  
  Concurrent Execution: The application or transaction is already running in the background or foreground.
  Job Scheduling: A background job has been scheduled to run at the same time, causing a conflict.
  Lock Entries: There may be lock entries in the database that prevent the application from starting.
  User Session: The same user or another user may have an active session that is executing the same application.
  
  Solutions:
  
  
  Check Running Processes:
  
  Use transaction codes like SM37 (for background jobs) or SM50 (for active processes) to check if the application is already running.
  If you find an active instance, you may need to wait for it to complete or terminate it if it is stuck.
  
  
  
  Review Job Scheduling:
  
  If the application is scheduled as a background job, check the job scheduling settings to avoid conflicts.
  You can adjust the scheduling to ensure that jobs do not overlap.
  
  
  
  Clear Lock Entries:
  
  Use transaction SM12 to check for and delete any unnecessary lock entries that may be causing the issue.
  Be cautious when deleting locks, as this can affect other users or processes.
  
  
  
  User Sessions:
  
  Check if the same user is logged in multiple times and running the same transaction. If so, log out from one of the sessions.
  
  
  
  System Logs:
  
  Review system logs (transaction SM21) for any additional error messages or warnings that might provide more context about the issue.
