• What is the cause and solution for SAP error message 26402 - Error: Do not use the browser buttons ?

  The SAP error message 26402, which states "Do not use the browser buttons," typically occurs when users attempt to navigate through an SAP web application using the browser's back, forward, or refresh buttons. This can lead to unexpected behavior, such as loss of data or session issues, because the web application may not handle these actions properly.

  Solution:
  
  Use In-App Navigation: Always use the navigation buttons provided within the SAP application (like "Back," "Next," or "Home") instead of the browser's buttons.
  Refresh with Caution: If you need to refresh the page, use the refresh button within the SAP application if available, or navigate back to the desired screen using the application’s navigation options.
  Bookmarking: If you need to return to a specific screen, consider bookmarking the page within the SAP application rather than using the browser's bookmark feature.
  Training and Awareness: Educate users about the proper navigation methods within SAP applications to prevent this error from occurring.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any updates or patches related to this error message. SAP frequently releases updates that may address navigation issues.
