步骤1：在component里引用OVS component
DEPT_OVS WDR_OVS System Component for OVS Input Help
OVS WDR_OVS System Component for OVS Input Help
步骤2：在context 里的对应字段比如Z_CENTER_CD 的属性input help mode改为 object value selector 在OVS component usage里选择你刚才添加的OVS 名字
步骤3：
在对应的view里引用刚才的OVS component
步骤4：增加OVS事件EVENT hander
步骤5：修改自动生成的代码
