• What is the cause and solution for SAP error message ICF_SYSTEM_LOGIN002 - Logon through HTTP is not possible; logon ticket is active for HTTPS only ?

  The SAP error message ICF_SYSTEM_LOGIN002 indicates that there is an issue with the logon method being used for accessing the SAP system. Specifically, it means that the logon ticket is valid only for HTTPS connections, and an attempt is being made to log in via HTTP.
  Cause:
  
  Logon Ticket Configuration: The system is configured to accept logon tickets only for secure connections (HTTPS). If a user tries to log in using an unsecured connection (HTTP), the system will reject the request.
  Web Dispatcher or Reverse Proxy Settings: If you are using a Web Dispatcher or a reverse proxy, it may not be correctly configured to handle HTTPS requests, leading to HTTP requests being sent instead.
  URL Mismatch: The URL used to access the SAP system may be incorrect, leading to an HTTP request instead of HTTPS.
  
  Solution:
  
  Use HTTPS: Ensure that you are accessing the SAP system using HTTPS instead of HTTP. Update the URL in your browser or application to use https:// instead of http://.
  Check Configuration: 
  
  Verify the configuration of the SAP system to ensure that it is set up to accept HTTPS connections.
  If using a Web Dispatcher or reverse proxy, check its configuration to ensure it is forwarding requests correctly and that SSL is properly set up.
  
  
  SAP System Settings:
  
  Go to transaction SICF in the SAP GUI.
  Navigate to the service you are trying to access and check the settings to ensure that it is enabled for HTTPS.
  
  
  Browser Settings: Ensure that your browser is not forcing HTTP connections. Check for any settings or extensions that might be redirecting HTTPS requests to HTTP.
  Network Configuration: If you are behind a firewall or proxy, ensure that it allows HTTPS traffic to the SAP system.
