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.

Hi dhanya,

am sorry for that..my mistake..

however try these fm's

EPS_GET_DIRECTORY_LISTING ---puts result into internal table but doesnt prompt...

SAPDMC/LSM_F4_SERVER_FILE --prompts for the selecvtion

hope this helps u a bit,

all the best,
