上面代码中this.SourceObject = BusinessDataServiceHelper.LoadSingle(this.Context, openParameter.PkValue, srcBusinessInfo, null);获取一个单据的数据包，但是获得的SourceObject其中的数据相当有限， srcBusinessInfo中单据头至少有上百个字段，而SourceObject中实际存储的只有几十个字段，那剩下的字段数据如何获取，我这边实际碰到的问题是要加载发货通知单中的“结算币别”字段，但在SourceObject中找了很多遍发现并没有该字段，想请教下各位老师和大神结算币别这个字段的数据如何获取，也包括没有在SourceObject的其他字段存放在哪，如何获取，谢谢了
