• What is the cause and solution for SAP error message ITS038 - Number of Web GUI requests ?

  The SAP error message ITS038, which indicates "Number of Web GUI requests," typically occurs when the number of concurrent requests to the SAP Web GUI exceeds the configured limit. This can happen in environments where many users are accessing the system simultaneously, leading to performance issues or resource exhaustion.
  Cause:
  
  High User Load: A large number of users trying to access the SAP system at the same time can lead to exceeding the maximum number of allowed concurrent requests.
  Configuration Limits: The system may have been configured with a low limit for concurrent Web GUI requests.
  Session Management: Inefficient session management or not properly closing sessions can lead to an accumulation of open requests.
  Network Issues: Network latency or issues can cause requests to hang, leading to a backlog of requests.
  
  Solution:
  
  
  Increase the Limit: 
  
  You can increase the maximum number of concurrent requests allowed for the Web GUI. This can be done in the SAP system configuration settings. The parameter to adjust is typically found in the SAP Web Dispatcher or SAP ITS settings.
  For example, you can adjust the parameter max_connections in the Web Dispatcher configuration.
  
  
  
  Optimize User Sessions:
  
  Ensure that users are properly logging out of sessions when they are done. Implement session timeout settings to automatically close inactive sessions.
  Monitor and manage user sessions to prevent excessive open sessions.
  
  
  
  Load Balancing:
  
  If applicable, consider implementing load balancing to distribute user requests across multiple application servers, which can help manage the load more effectively.
  
  
  
  Performance Monitoring:
  
  Use SAP monitoring tools to analyze the performance and identify bottlenecks. This can help in understanding the load patterns and making informed decisions about scaling resources.
  
  
  
  Review Network Configuration:
  
  Ensure that the network infrastructure is capable of handling the expected load and that there are no issues causing delays in request processing.
