How to create open file dialog for choosing file in application server?

I would like to have the same functionality as

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.

CALL FUNCTION 'NAVIGATION_FILENAME_HELP'

EXPORTING

DEFAULT_PATH = '.'

MODE = 'O'

IMPORTING

RETURNCODE = return_code

SELECTED_FILENAME = p_file.

But the above code, only allow me to choose files from local computer. How to do the same thing with the file location becomes the application server?

Thanks!
