REUSE_ALV_GRID_DISPLAY 事件实现（DATA_CHANGED）

1. 实现步骤

• 设置SAP回调参数，并在REUSE_ALV_GRID_DISPLAY中应用参数

    DATA: ls_grid_settings TYPE lvc_s_glay.
    ls_grid_settings-edt_cll_cb = abap_true.      "开启单元格回调
  

  

• 设置DATA_CHANGED事件，并在REUSE_ALV_GRID_DISPLAY中应用参数

• REUSE_ALV_EVENTS_GET能获取到的事件就修改，不能获取的则需APPEND新增

    DATA: gt_eve TYPE slis_t_event.
    DATA : wa_eve TYPE slis_alv_event.
    DATA: slis_ev_data_changed TYPE slis_formname VALUE 'DATA_CHANGED'.
  
    CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
      EXPORTING
        i_list_type     = 0
      IMPORTING
        et_events       = gt_eve
      EXCEPTIONS
        list_type_wrong = 1
        OTHERS          = 2.
  
    IF sy-subrc = 0.
      wa_eve-name =  slis_ev_data_changed.
      wa_eve-form = 'FRM_DATA_CHANGED'.
      APPEND wa_eve TO gt_eve.
    ENDIF.
  

  

• 实现事件

  FORM frm_data_changed USING lrc_i_dc TYPE REF TO cl_alv_changed_data_protocol.
    DATA: lt_alv_mod TYPE TABLE OF ty_data,
          wa_alv_mod TYPE ty_data.
    FIELD-SYMBOLS: <fs_tab_mod> TYPE table,
                   <fs_wa> TYPE ty_data.
    DATA: lr_grid TYPE REF TO cl_gui_alv_grid.
  
    "将变更的数据刷新
    CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
      IMPORTING
        e_grid = lr_grid.
  
    ASSIGN lrc_i_dc->mp_mod_rows->* TO <fs_tab_mod>.
    lt_alv_mod = <fs_tab_mod>.
    LOOP AT lt_alv_mod INTO wa_alv_mod.
      IF wa_alv_mod-sel = abap_true.
        LOOP AT gt_data ASSIGNING <fs_wa> WHERE mblnr = wa_alv_mod-mblnr.
          <fs_wa>-sel = 'X'.
        ENDLOOP.
      ELSE.
        LOOP AT gt_data ASSIGNING <fs_wa> WHERE mblnr = wa_alv_mod-mblnr.
          CLEAR: <fs_wa>-sel.
        ENDLOOP.
      ENDIF.
    ENDLOOP.
  
    CALL METHOD lr_grid->refresh_table_display.
  
  ENDFORM.                    " FRM_DATA_CHANGED
  

2. 效果

• 实现数据的同步勾选
