1.在alv界面表单属性中设置
if wa_fieldcat-fieldname = 'YC_MARK'.
wa_fieldcat-edit = 'X'.
wa_fieldcat-drdn_field = 'DD_HANDLE'.
wa_fieldcat-drdn_hndl = '1'.
endif.
2.给下拉框赋值
LTH_LIST-HANDLE = '1' .
LTH_LIST-VALUE = 'N' .
APPEND LTH_LIST TO TD_LIST.
CLEAR LTH_LIST.
LTH_LIST-HANDLE = '1' .
LTH_LIST-VALUE = 'Y'.
APPEND LTH_LIST TO TD_LIST.
CLEAR LTH_LIST.
3.设置IT_events
data:lt_event type table of slis_alv_event,
lw_event type slis_alv_event.
perform alv_fieldcat.
it_layout-cwidth_opt = 'X'.
it_layout-box_fname = 'SEL'.
lw_event-name = 'CALLER_EXIT'.
lw_event-form = 'SET_LIST'.
append lw_event to lt_event.
call function 'REUSE_ALV_GRID_DISPLAY_LVC'
exporting
i_callback_program = sy-repid
i_callback_pf_status_set = 'PF_STATUS '
i_callback_user_command = 'USER_COMMAND'
is_layout_lvc = it_layout
it_fieldcat_lvc = it_fieldcat
it_events = lt_event
tables
t_outtab = gt_excel
exceptions
program_error = 1
others = 2.
4.将下拉框赋值给ALV界面字段
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING
E_GRID = LW_GRID.
CALL METHOD LW_GRID->SET_DROP_DOWN_TABLE
EXPORTING
IT_DROP_DOWN = TD_LIST.
