Hola:

Pues si es posible hacer la descarga mediante la funcion GUI_DOWNLOAD..
te envio un ejemplo, espero que te sirva:

DATA: BEGIN OF ti_texto OCCURS 0,
linea(500) TYPE c,
END OF ti_texto.


DATA: V_SEP TYPE C VALUE ','.
DATA: BEGIN OF TI_INTERNA OCCURS 0,
CARRID TYPE S_CARR_ID,
CONNID TYPE S_CONN_ID,
FLDATE TYPE S_DATE,
END OF TI_INTERNA.

FIELD-SYMBOLS: <fs_INTERNA> LIKE LINE OF TI_INTERNA.
SELECT CARRID CONNID FLDATE
INTO TABLE TI_INTERNA
FROM SFLIGHT.

LOOP AT ti_INTERNA ASSIGNING <fs_INTERNA>.

CONCATENATE
<fs_INTERNA>-CARRID
<fs_INTERNA>-CONNID
<fs_INTERNA>-FLDATE
INTO ti_texto SEPARATED BY V_SEP.
APPEND ti_texto.
CLEAR: ti_texto.
ENDLOOP.
