Hi Ramesh,

You have to capture the event into for user_command which you can pass to alv grid function module. There you can call your function module to download the output.

Hi,

In the FM 'REUSE_ALV_GRID_DISPLAY' you can use the parameter 'i_callback_user_command ' to pass the user command form name to be called for handling events.

Following is the code snippet :

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_bypassing_buffer = 'X'

i_buffer_active = ' '

i_callback_program = w_repid

i_callback_user_command = 'USER_COMMAND' "form name to be executed

Define the form 'User_command' in the program to handle the events and code the logic for * different events(for different push buttons).

FORM user_command USING r_ucomm LIKE sy-ucomm

rs_selfield TYPE slis_selfield.

The field "R_UCOMM" will contain the current value of "SY-UCOMM"
"RS_SELFIELD" will hold contents of the selected line

CASE r_ucomm.

WHEN '&ZDL'.

CALL FUNCTION 'GUI_FILE_SAVE_DIALOG'

EXPORTING

.......

IMPORTING

..........

ENDCASE.

ENDFORM. "USER_COMMAND

Hope this information helps..

Regards,

Dilli
