需求，输入航线代码和航线编号区间，查询记录存在表中显示，并不是alv显示

1、使用组件WDR_SELECT_OPTIONS.

2.在组件控制器中加入以下组件

3、在视图属性中也添加该组件

4、创建节点

5、控件设计

6、窗口下的视图中嵌套这个视图

7、设计视图初始化方法WDDOINIT

method WDDOINIT .DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.  lo_cmp_usage = wd_this->wd_cpuse_select_options( ).  IF lo_cmp_usage->has_active_component( ) IS INITIAL.    lo_cmp_usage->create_component( ).  ELSE.    EXIT.  ENDIF.*---选择屏幕的引用  DATA lo_interfacecontroller TYPE REF TO iwci_wdr_select_options .  lo_interfacecontroller =   wd_this->wd_cpifc_select_options( ).  "修改SELECT_OPTIONS  wd_this->m_handler = lo_interfacecontroller->init_selection_screen(   ).*---设置全局信息  CALL METHOD wd_this->m_handler->set_global_options    EXPORTING      i_display_btn_cancel  = abap_false      i_display_btn_check   = abap_false      i_display_btn_reset   = abap_false      i_display_btn_execute = abap_false.  DATA: lr_field TYPE REF TO data.  DEFINE mcr_sel.    free lr_field.    lr_field = wd_this->m_handler->create_range_table( &1 ).    wd_this->m_handler->add_selection_field(      i_id = &1                                "字段参考类型      i_description = &2                       "描述      it_result = lr_field      i_read_only = &3 ).  END-OF-DEFINITION.  mcr_sel 'S_CARR_ID' '航线代码' abap_false.  mcr_sel 'S_CONN_ID' '航班编号' abap_false.endmethod.

8、设计按钮SEARCH事件方法

method ONACTIONSEARCH .*获取SELECT OPTIONS  FIELD-SYMBOLS: 
     
       TYPE ANY TABLE,                 
      
        TYPE ANY TABLE.  DATA lv_CARRID TYPE S_CARR_ID .          "屏幕上输入的  DATA lv_CONNID TYPE S_CONN_ID .          "屏幕上输入的  DATA:lo_data TYPE REF TO data.  FREE lo_data.  lo_data = wd_this->m_handler->get_range_table_of_sel_field( 'S_CARR_ID' ).  ASSIGN lo_data->* TO 
       
        .  FREE lo_data.  lo_data = wd_this->m_handler->get_range_table_of_sel_field( 'S_CONN_ID' ).  ASSIGN lo_data->* TO 
        
         .*数据绑定  DATA lo_nd_sflight TYPE REF TO if_wd_context_node.  DATA lo_el_sflight TYPE REF TO if_wd_context_element.  DATA lt_sflight TYPE wd_this->Elements_sflight.  lo_nd_sflight = wd_context->get_child_node( name = wd_this->wdctx_sflight ).  SELECT * INTO TABLE lt_sflight from sflight    WHERE CARRID in 
         
              AND   CONNID in 
          
           . lo_nd_sflight->BIND_TABLE( NEW_ITEMS = lt_sflight ).endmethod.
          
         
        
       
      
     

9、效果展示
