• What is the cause and solution for SAP error message WEBDYNPRO_RT011 - Number of called sessions ?

  SAP Error Message:
  
  WEBDYNPRO_RT011 – Number of called sessions
  
  Cause:
  This error occurs when the number of Web Dynpro sessions called or opened exceeds the allowed or configured limit. In SAP Web Dynpro applications, there is a restriction on how many sessions or windows can be opened simultaneously for a user or a particular application. When this limit is exceeded, the system throws the error WEBDYNPRO_RT011.
  This is typically caused by:
  
  Users opening multiple browser windows or tabs running the same Web Dynpro application.
  Programmatic calls that open multiple sessions without proper session management.
  Long-running sessions not being closed properly, leading to accumulation of active sessions.
  System configuration limits on the maximum number of sessions per user or per application.
  
  
  Solution:
  To resolve the WEBDYNPRO_RT011 error, consider the following steps:
  
  
  Check and Adjust Session Limits:
  
  Review the system profile parameters related to Web Dynpro session limits.
  Parameters like icm/keep_alive_timeout or Web Dynpro-specific settings might influence session handling.
  In some cases, the limit is controlled by the Web Dynpro application or framework settings.
  
  
  
  User Behavior:
  
  Advise users to avoid opening multiple instances of the same Web Dynpro application in different browser tabs or windows.
  Encourage closing unused sessions or windows.
  
  
  
  Programmatic Handling:
  
  Review the Web Dynpro application code to ensure it does not open unnecessary new sessions.
  Implement proper session management and cleanup in the application logic.
  
  
  
  System Cleanup:
  
  Use transaction SM04 or AL08 to monitor and manage user sessions.
  Administrators can terminate stale or inactive sessions to free up session slots.
  
  
  
  Web Dynpro Configuration:
  
  Check the Web Dynpro application configuration in transaction SE80 or WDA tools.
  Look for settings related to session management or window handling.

  Summary:
