Hi,
The URL Parameters are available in the parameter WDEVENT in the window.
in your webdynpro component, you have a window for every application(URL).
in that window, you have an event handler HANDLEDEFAULT.
in the event handler, you will find an import parameter called WDEVENT type ref to CL_WD_CUSTOM_EVENT.
you can read the url parameter with get_data method.
wdevent->get_data( Exporting name = 'URL_Param' importingvalue = lv_URL_param ).
even if the url paramenters are not visible in the URL, you can read them in the windoe method.
Thanks.
