i need the windows user in an ABAP Webservice.
I have found many solutions (e.g. cl_gui_frontend_services->get_user_name or function modules GUI_GET_DESKTOP_INFO, WS_QUERY ....)
But these solutions are only working if you are connected via SAP GUI to the SAP system.
I want to trigger the web service not via SAP GUI.
Is there a possiblility to get the Windows user in ABAP without the need of the SAP GUI?
