• What is the cause and solution for SAP error message FRE165 - No Work Processes for Parallel Processing available. Processing Aborted. ?

  The SAP error message FRE165: No Work Processes for Parallel Processing available. Processing Aborted. typically occurs when there are no available work processes in the SAP system to handle parallel processing requests. This can happen for several reasons, including system configuration issues, resource limitations, or high system load.
  Causes:
  
  Insufficient Work Processes: The number of work processes configured in the SAP system may be too low to handle the current workload.
  High System Load: The system may be experiencing high load, causing all available work processes to be busy.
  Configuration Issues: The configuration settings for parallel processing may not be set correctly.
  Resource Limitations: The underlying hardware or operating system may be limiting the number of processes that can be executed concurrently.
  Long-running Jobs: There may be long-running jobs that are occupying the work processes, preventing new requests from being processed.
  
  Solutions:
  
  
  Increase Work Processes:
  
  Go to transaction RZ10 to adjust the profile parameters for the instance.
  Increase the number of work processes (e.g., dialog, background, update) as needed.
  Restart the SAP instance for the changes to take effect.
  
  
  
  Monitor System Load:

  Ensure that the parameters related to parallel processing (like rdisp/wp_no_dia, rdisp/wp_no_btc, etc.) are configured appropriately.
  
  
  
  System Resources:
  
  Check the underlying hardware resources (CPU, memory, etc.) to ensure that the system is not resource-constrained.
  If necessary, consider upgrading the hardware or optimizing the system performance.
  
  
  
  Review Job Scheduling:
  
  Use transaction SM37 to review scheduled jobs and their statuses.
