• What is the cause and solution for SAP error message GR354 - Parallel report & is used repeatedly ?

  The SAP error message GR354 ("Parallel report & is used repeatedly") typically occurs when a report is being executed in parallel processing mode, and the system detects that the same report is being called multiple times simultaneously. This can lead to performance issues or conflicts in data processing.
  Cause:
  
  Parallel Processing: The report is designed to run in parallel, but it is being triggered multiple times for the same data set or parameters.
  Job Scheduling: If the report is scheduled to run at overlapping times, it can lead to this error.
  User Actions: Users may inadvertently trigger the same report multiple times, either through manual execution or through batch jobs.
  
  Solution:
  
  Check Job Scheduling: Review the job scheduling settings to ensure that the report is not scheduled to run at overlapping times. Adjust the schedule to avoid conflicts.
  Limit Parallel Execution: If possible, modify the report settings to limit the number of parallel executions. This can often be done in the report's configuration or by adjusting the job parameters.
  User Training: Educate users on the proper execution of reports to avoid unintentional multiple executions.
  Monitor Background Jobs: Use transaction codes like SM37 to monitor background jobs and identify if the same report is being executed multiple times.
  Modify Report Logic: If you have access to the report's code, consider adding logic to check if an instance of the report is already running before allowing another instance to start.
