• What is the cause and solution for SAP error message /PM0/ABJ_MSG803 - &1 / &2 is already in process; new persistent application is not possible ?

  The SAP error message /PM0/ABJ_MSG803 &1 / &2 is already in process; new persistent application is not possible typically indicates that there is an attempt to start a new instance of a persistent application (like a background job or a transaction) that is already running. This can happen in various scenarios, such as when a user tries to execute a transaction that is already being processed or when a job is scheduled to run but is still in progress.
  Cause:
  
  Concurrent Execution: The application or job you are trying to start is already running. SAP does not allow multiple instances of the same persistent application to run simultaneously to avoid data inconsistencies.
  Job Overlap: If you have scheduled jobs that overlap in their execution time, this error can occur.
  Session Management: Sometimes, if a session is not properly closed or terminated, it may still be considered active by the system.
  
  Solution:
  
  Check Running Instances: Use transaction codes like SM37 (Job Monitoring) to check if the job or application is currently running. If it is, you may need to wait for it to complete.
  Terminate the Job: If you find that the job is stuck or taking too long, you can terminate it from the job monitoring screen.
  Avoid Overlapping Jobs: If you are scheduling jobs, ensure that they do not overlap in their execution times. Adjust the scheduling times accordingly.
  Session Cleanup: If you suspect that a session is still active, you can log out and log back in, or use transaction SM04 to check for active user sessions and terminate any unnecessary ones.
  Review Application Logic: If this error occurs frequently, review the application logic to ensure that it handles concurrent executions properly.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM37 (Job Monitoring), SM04 (User Sessions), and SM21 (System Log) for monitoring and troubleshooting.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. Sometimes, specific versions of SAP may have bugs that are documented in SAP Notes.
  Documentation: Review the documentation for the specific application or module you are working with to understand its behavior regarding job execution and concurrency.
