Smart SAP Assistant

• What is the cause and solution for SAP error message IU620 - No displayable work processes on application server & ?

  The SAP error message IU620 "No displayable work processes on application server" typically indicates that the SAP application server is unable to find any available work processes to handle the request. This can occur for several reasons, and understanding the cause is essential for troubleshooting and resolving the issue.
  Causes:
  
  Work Process Configuration: The application server may not have any work processes configured or all work processes may be busy or in a non-operational state.
  System Load: The server may be under heavy load, causing all available work processes to be occupied with other tasks.
  Resource Limitations: Insufficient system resources (CPU, memory) can lead to work processes being unable to start.
  System Errors: There may be underlying issues with the SAP system or the operating system that prevent work processes from being created or maintained.
  Network Issues: Problems with network connectivity can also lead to issues with work processes being displayed or accessed.
  
  Solutions:
  
  
  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 the number of work processes is configured correctly based on your system's requirements.
  
  
  
  Monitor System Load:
  
  Use transaction SM50 to monitor the status of work processes. Check if they are busy or in a waiting state.
  If the system is overloaded, consider optimizing the workload or increasing the number of work processes.
  
  
  
  Check System Resources:
  
  Use operating system tools to monitor CPU and memory usage. Ensure that the server has enough resources to handle the workload.
  If necessary, allocate more resources or optimize existing resource usage.
  
  
  
  Review System Logs:
  
  Check the system logs using transaction SM21 for any errors or warnings that might indicate issues with the application server or work processes.
  Look for any relevant messages that could provide insight into the problem.
  
  
  
  Restart the Application Server:
  
  If the issue persists, consider restarting the application server. This can help clear any temporary issues that may be affecting work processes.
  
  
  
  Check Network Connectivity:
  
  Ensure that there are no network issues affecting the connection to the application server. Check firewalls, routers, and other network components.
  
  
  
  Consult SAP Notes:
  
  Search for relevant SAP Notes in the SAP Support Portal that may address specific issues related to work processes and the IU620 error.
