Use gui_upload method of CL_GUI_FRONTEND_SERVICES class...

anything you want to do between AS and presentation layer, please use methods of this class...

Hi Sampath

I think F4_FILENAME for the user to search for the file

and WS_UPLOAD to upload from "Presentation Server".

I m looking for Application Server.
