  Cause:
  
  Work Process Configuration: The system may not have enough work processes configured to handle the job. This can happen if the system is under heavy load or if the configuration settings for work processes are not optimal.

  Solution:
  
  
  Check Work Process Configuration:
  
  Go to transaction RZ10 and check the profile parameters related to work processes (e.g., rdisp/wp_no_dia, rdisp/wp_no_btc, etc.).
  Ensure that there are enough dialog and background work processes configured for the expected workload.
  
  
  
  Monitor System Load:
