WDA 新SELECT OPTION

感谢肖总的提示，不然还不知道wda的新select option。。。

使用前提：SE24类：CL_WDR_SELECT_OPTIONS_20

核对了多个版本，ERP系统版本要S4 1701往上，CRM系统7 EHP3及以上，没有怎么管这个，不对也别怪我。。。

SE80，查看SELECT OPTION的组件：WD_SELECT_OPTIONS_20是否存在，如果不存在则不能使用。

1.新建WDA组件ZLYTEST_SELECT,并激活

2.双击WDA添加SELECT OPTION组件和ALV组件。

3。双击COMPONENTCONTROLLER，添加查询结果节点。结构预先定义。

4.双击V_MAIN视图，将ALV组件和SELECT OPTION添加到视图中。布局中添加两个UI element

5.初始化alv和select option对象

将ALV和select option初始化的方法加到WDA视图的WDDOINIT里

6.在WINDOW里绑定视图下面的UI对象和组件

7.将ALV数据对象绑定COMPONENTCONTROLLER结果节点

8.创建application，并测试。结果如下：

9.SELECT OPTION的查询参数处理和结果绑定
