• What is the cause and solution for SAP error message SY479 - Expiration date of session & extended ?

  The SAP error message SY479, which states "Expiration date of session & extended," typically occurs when a user session in SAP has exceeded its allowed duration or has been inactive for a period that exceeds the configured timeout settings. This can happen in various scenarios, such as when a user is logged in but not actively using the system for a certain period.
  Cause:
  
  Session Timeout: The session has been inactive for longer than the configured timeout period.

  Solution:
  
  Re-login: The simplest solution is to log out and log back into the SAP system. This will create a new session.
  Check Timeout Settings: If you have administrative access, check the timeout settings in the SAP system. You can adjust the session timeout settings in the profile parameters (e.g., rdisp/gui_auto_logout).

  User Training: Educate users about the importance of logging out when not in use and the implications of leaving sessions open.
