Application server file problem

Hi Friends,

I want to upload the XML file from the application server.

I have written the code like

OPEN DATASET filename FOR INPUT IN TEXT MODE.

IF sy-subrc EQ 0.

DO.

READ DATASET int_filename-filename INTO int_records.

ENDDO.

ENDIF.

CLOSE DATASET.

After OPEN dataset I am getting the sy-subrc = 8.It's not opening the file.

Please suggest me how we can do this.

Thnx,

Sam.
