Heloo,

For catching the events u need to set the handler

SET HANDLER lcl_alv_toolbar =>USER_COMMAND FOR toolbar.

HI frnd ,

JST TRY THIS SMALL CODE .

REPORT ZPRI_ALV8.

type-pools : slis .

data: v_repid like sy-repid .

data: itab like mara occurs 0 with header line .

data: itab1 like makt occurs 0 with header line .

break devuser .

select * from mara into table itab .

v_repid = sy-repid .

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

I_CALLBACK_PROGRAM = v_repid

I_CALLBACK_USER_COMMAND = 'DISPLAY_DOCUMENT '

I_STRUCTURE_NAME = 'mara'

TABLES

t_outtab = itab

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

*****************************************************

FOR DISPLAYING sECONDRY LIST .

FORM DISPLAY_DOCUMENT USING R_UCOMM LIKE SY-UCOMM

RS_SELFIELD TYPE SLIS_SELFIELD.

IF RS_SELFIELD-FIELDNAME = 'MATNR'.

READ TABLE ITAB INDEX RS_SELFIELD-TABINDEX .

select * from makt into table itab1 where matnr = itab-matnr .

IF SY-SUBRC = 0 .

ENDIF .

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

I_STRUCTURE_NAME = 'makt'

TABLES

T_OUTTAB = ITAB1

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

endif.

ENDFORM.

THIS code will definetly help you to understand intractive alv ...
