check this sample code...

this is for uploading data into apllicn server

OPEN DATASET <file name> FOR {OUTPUT/INPUT/APPENDING}

chk this program..

DATA: i_file like rlgrap-filename value '/usr/sap/tmp/file.txt'.

OPEN DATASET i_file FOR INPUT IN TEXT MODE.

IF sy-subrc NE 0.

ENDIF.

DO.

• Reads each line of file individually

READ DATASET i_file INTO wa_datatab.

• Perform processing here
