1. 定义和注册事件接受器类
*----------------------------------------------------------------------* * CLASS LCL_EVENT_RECEIVER DEFINITION DEFERRED *----------------------------------------------------------------------* * LCL_EVENT_RECEIVER *----------------------------------------------------------------------* CLASS lcl_event_receiver DEFINITION DEFERRED. DATA gv_flg TYPE char01. *----------------------------------------------------------------------* * CLASS LCL_EVENT_RECEIVER DEFINITION *----------------------------------------------------------------------* * lcl_event_receiver的类定义： *----------------------------------------------------------------------* CLASS lcl_event_receiver DEFINITION.

2. 调用alv函数
**EVENT LAYOUT DATA: ls_events TYPE slis_alv_event, lt_event TYPE slis_t_event, ls_layout TYPE lvc_s_layo. ls_events-name = 'CALLER_EXIT'. ls_events-form = 'FM_BUTTON'.

3. 定义是事件子程序
*&---------------------------------------------------------------------* *& Form FM_BUTTON *&---------------------------------------------------------------------* * 设置enter事件 *----------------------------------------------------------------------* * -->E_GRID text *----------------------------------------------------------------------* FORM fm_button USING e_grid TYPE slis_data_caller_exit.

SET HANDLER lv_event_receiver->handle_f4 FOR tem_grid. CALL METHOD tem_grid->register_f4_for_fields EXPORTING it_f4 = lt_f4[]. ENDFORM. "FM_BUTTON
4. 定义alv-status子程序
*&---------------------------------------------------------------------* *& Form PF_STATUS_SET *&---------------------------------------------------------------------* * status设定 *----------------------------------------------------------------------* * -->RT_EXTAB text *----------------------------------------------------------------------* FORM pf_status_set USING rt_extab TYPE slis_t_extab.

5. 定义alv-comman子程序

6. 其他子程序定义
