2626799 - Getting error when trying to Open WebGUI and WebDynpro Apps


  • An SAP Web Dispatcher is used as an entry point for a Fiori landscape.
  • The SAP Web Dispatcher was configured per the relevant Fiori / UI Technology Guide.
  • Besides using Fiori, other Web UI (User Interface) technologies are being used (like the WebGUI/ITS or WebDynpro).
  • However, they do not work correctly if the access is performed through the Web Dispatcher (for example, the logon page does not work, dropdown menus do not work, ...).
  • Direct access to the backend presents no issues.
