Hi,
In background the GUI_DOWNLOAD FM fails...so u have to use OPEN DATASET .so that ur file will be downloaded to application server....
   Internal table to display error contracts  .
     i_error         TYPE STANDARD TABLE OF t_error.
Declaration of local variables
  DATA : lv_dsn3(1000) TYPE c,
         lv_dsn4(1000) TYPE c.
IF NOT i_error IS INITIAL.
      LOOP AT i_error INTO wa_error.
        CONCATENATE  wa_error-lifnr
                     wa_error-evart
                     wa_error-vedat
                     wa_error-ekorg
                     wa_error-ekgrp
                     wa_error-epstp
                     wa_error-knttp
                     wa_error-bukrs
                     wa_error-kdatb
                     wa_error-kdate
                     wa_error-ktwrt
                     wa_error-waers
                     wa_error-wkurs
                     wa_error-inco1
                     wa_error-inco2
                     wa_error-ihran
                     wa_error-angnr
                     wa_error-msg
                     INTO wa_input1 SEPARATED BY c_tab .
        APPEND wa_input1 TO i_input1.
        CLEAR : wa_input1,
                wa_error.
      ENDLOOP.
Move the contract error files to the application server
      CONCATENATE v_fname1(15) lc_path1 p_aerfl1 INTO lv_dsn3.
      OPEN DATASET lv_dsn3 FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
      CHECK sy-subrc EQ 0.
      LOOP AT i_input1 INTO wa_input1.
        TRANSFER wa_input1 TO lv_dsn3.
      ENDLOOP.
      CLOSE DATASET lv_dsn3.
    ENDIF.
