How to do a drill down whit 'REUSE_ALV_GRID_DISPLAY'

Question

Hi Guru,
i must do a drill down with 2 field of a 'REUSE_ALV_GRID_DISPLAY'
this is the program:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
   EXPORTING
    I_INTERFACE_CHECK                 = ' '
    I_BYPASSING_BUFFER                = ' '
    I_BUFFER_ACTIVE                   = ' '
    I_CALLBACK_PROGRAM                = ' '
    I_CALLBACK_PF_STATUS_SET          = ' '
    I_CALLBACK_USER_COMMAND           = ' '
     IT_FIELDCAT                        = tabcatalogo
    TABLES
      t_outtab                          = appoggio
where
TYPE-POOLS slis.
DATA : tabcatalogo TYPE slis_t_fieldcat_alv,
      rec_tabcatalogo TYPE slis_fieldcat_alv.
TABLES: viob03,
        viob37,
        ekkn,
        ekko.
DATA : BEGIN OF appoggio OCCURS 0,
       bukrs LIKE viob03-BUKRS,
       swenr LIKE viob03-swenr,
       j_objnr LIKE viob03-j_objnr,
       sgenr LIKE viob03-sgenr,
       anln1 LIKE viob37-anln1,
       anln2 LIKE viob37-anln2,
       ebeln LIKE ekkn-ebeln,
       kdatb LIKE ekko-kdatb,
       kdate LIKE ekko-kdate,
       END OF appoggio.
THE FIELD FOR DRILL DOWN ARE swenr  AND  anln1
Thanks and sorry for my english
