Hi,

You can make the Selection screen field as mandatory first. because without file, no upload takes place.

Next before calling the fun module GUI_UPLOAD.write like this.

if not p_file is initial. (for file)

or it not itab[] is initial. (for Int table)

call function gui_upload

...

endif,.

regards,

Anji

Hi Sushant,

If you want to know " Whether the file is empty or not ", before uploading a file from presentation server.Use Function Module <b>WS_QUERY</b>,

in this Function Module you can see one parameter "QUERY", in that you can put

either CD' 'FE' 'FL' 'EN' 'WI' 'WS' ....... .Here <b>FL</b> is nothing but a file length. Set paramter as FL so that you will get <b>File Size</b> before uploading a file from presentation server.OK.

Reward,if helps.

IF p_file NP c_file_extn .

MESSAGE File should be in *.XLS format

ENDIF.

Here P_FILE is the parameter for File on selection Screen.
