Problem in the internal table of open dataset statement

Question

Hi abapers,
I am using the open dataset command to download my file at application server into an internal table.
But some colums of the internal table are string since i do not want to truncate any of the long text present in the file.
The open dataset command does not allow the internal table to have string components.
Is there any workaround by which i can download all the text components of the file without truncating them .
Regards,
Aditya

try to use field symbols:-
FORM download_file  .
  DATA: l_file TYPE  rlgrap-filename,
        l_line TYPE string.
  DATA: v_excel_string(1000) TYPE c,
          v_len TYPE i,
          v_zover TYPE i .
  FIELD-SYMBOLS: <f>     TYPE ANY .
  CLEAR wa_fin.
*--- Seting File path
  CONCATENATE p_cfile v_file sy-datum INTO l_file.
*--- Open data set
  OPEN DATASET l_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
  IF sy-subrc = 0.
    LOOP AT it_down INTO wa_down.
      CLEAR : v_excel_string, v_zover, v_len.
      DO.
        ASSIGN COMPONENT sy-index OF STRUCTURE wa_down TO <f>.
        IF sy-subrc <> 0.
          EXIT. "exits do loop and process next record in itab
        ENDIF.
        DESCRIBE FIELD <f> LENGTH v_len IN CHARACTER MODE.
        v_excel_string+v_zover(v_len) = <f> .
        v_zover = v_zover + v_len .
      ENDDO.
      TRANSFER v_excel_string TO l_file.
      CLEAR : v_excel_string,
              wa_down       ,
              v_zover       .
    ENDLOOP.
*--- Close data set
    CLOSE DATASET l_file.
    IF sy-subrc = 0.
*--- Success Message
     MESSAGE s000(000) WITH text-018.
    ENDIF.
  ELSE.
*--- Error unable to open file.
    MESSAGE e000(000) WITH text-017.
  ENDIF.
ENDFORM.                    " DOWNLOAD_FILE
