SAP ALV DATA_CHANGED_FINISHED事件实现后排序筛选等按钮弹窗异常的解决方法（筛选排序等按钮）

实现DATA_CHANGED_FINISHED功能后，筛选排序等按钮弹窗异常过滤条件不能自动带入选中的列

• 异常
  
• 正常
  

修正步骤

1. LCL_EVENT_RECEIVER定义中设置PRIVATE变量REFRESH
2. 实现 DATA_CHANGED 事件，并在事件中设置REFRESH = ‘X’.
3. 实现 DATA_CHANGED_FINISHED 事件，并在事件中判断REFRESH值，决定是否刷新ALV
4. 注册 DATA_CHANGED DATA_CHANGED_FINISHED 事件
