• What is the cause and solution for SAP error message ICF_SYSTEM_LOGIN402 - Logon with URL parameter not possible; logon cookie is missing ?

  The SAP error message ICF_SYSTEM_LOGIN402 indicates that a logon attempt to an SAP system via a URL parameter has failed because the required logon cookie is missing. This typically occurs in scenarios where the system is configured to use HTTP or HTTPS for communication, and the session management relies on cookies for authentication.
  Cause:
  
  
  Missing Logon Cookie: The logon cookie, which is essential for maintaining the session state, is not present in the request. This can happen if:
  
  The user has not logged in yet.
  The session has expired.
  Cookies are disabled in the browser.
  The URL is being accessed directly without a proper session established.
  
  
  
  Incorrect URL: The URL being used may not be correctly formatted or may not include the necessary parameters for authentication.
  
  
  Session Management Configuration: The SAP system may have specific configurations regarding session management that require cookies for authentication.
  
  
  Solution:
  
  
  Log In Properly: Ensure that you are logging into the SAP system correctly. Access the initial login page and enter your credentials to establish a session.
  
  
  Check Browser Settings: Make sure that cookies are enabled in your web browser. If cookies are disabled, the session cannot be maintained, leading to this error.
  
  
  Use the Correct URL: Verify that you are using the correct URL to access the SAP system. Ensure that it includes all necessary parameters and is formatted correctly.
  
  
  Clear Browser Cache: Sometimes, clearing the browser cache and cookies can resolve issues related to session management.
  
  
  Check Session Timeout: If the session has timed out, you may need to log in again. Ensure that you are not leaving the session idle for too long.
  
  
  Review ICF Settings: If you have access to the SAP system configuration, check the Internet Communication Framework (ICF) settings to ensure that they are correctly configured for session management.
  
  
  Consult SAP Notes: If the issue persists, check for any relevant SAP Notes or documentation that may provide additional insights or solutions specific to your version of SAP.
