业务描述
用户需要在VL06O事务代码下进行批量交货过账，现有的筛选条件不太适用当前公司的业务，需要在报表中新增三个交货单增强字段，方便其筛选（选择屏幕没有加，用户在报表里用标准按钮功能自己筛选）
效果展示
操作步骤
1、扩展LIPOV结构字段
扩展完之后系统会自动带出likp增强字段，如果没有别的表字段就可以结束了
如果有别的表的增强字段
在DisplayALV之前把字段加到gt_outtab中即可
方法1：隐式增强->LV50QF1W->list_display_basic_list
form list_display_basic_list.

同样的方法给ct_postab中添加值
如果业务非要在选择屏幕加的话也可以，选择屏幕在一个INCLUDE里，里面也有隐式增强点，完事在DisplayALV之前在做一个筛选就行
