销售订单由于有一段时间用新变更单修改单价没有同步下游单据，导致销售出库单的单价与订单单价不一致， 现在需要做插件同步，
开始想用关联表来取， 不过由于有发货通知单， 这样就需要取两个关联表， 非常不方便， 偶尔之间发现销售出库单明细有个销售订单EntryId
这个不是销售订单的FentryID吗，由于EntryId是唯一的，可以直接从T_SAL_ORDERENTRY_F取出单价了，于是在明细行添加一个按钮
添加插件如下
#引入clr运行库
import clr
#添加对cloud插件开发的常用组件的引用
clr.AddReference('System')
clr.AddReference('System.Data')
clr.AddReference('Kingdee.BOS')
clr.AddReference('Kingdee.BOS.DataEntity')
clr.AddReference('Kingdee.BOS.Core')
clr.AddReference('Kingdee.BOS.App')
clr.AddReference('Kingdee.BOS.App.Core')
clr.AddReference('Kingdee.BOS.ServiceHelper')
#导入cloud基础库中的常用实体对象（分命名空间导入，不会递归导入）
