上篇文章是携带单据头多选基础资料字段，下面介绍单据转换-单据体携带多选基础资料字段，代码如下：
```
/// <summary>
/// 单据从源单到目标单已经转换完毕，输出最后的目标单数据包之前触发,
/// 此时，目标单数据包已经构建完毕，不会再有变动了
/// </summary>
/// <param name="e"></param>
/// <remarks>
/// 可以在此事件中，对目标单数据包进行最后的修订、补充
/// </remarks>
public override void AfterConvert(AfterConvertEventArgs e)
{
base.AfterConvert(e);
string TgtFieldKey = "FCESHI1";
string SrcFieldKey = "FCESHI2";
/*
* <0>数据准备
*/
MulBaseDataField tgtBaseDataField = e.TargetBusinessInfo.GetField(TgtFieldKey) as MulBaseDataField;
MulBaseDataField srcBaseDataField = e.SourceBusinessInfo.GetField(SrcFieldKey) as MulBaseDataField;
if (tgtBaseDataField == null || srcBaseDataField == null)
return;

return null;

};

/*
* <1>根据下游单据的数据包，和源单信息，填入多选基础资料
*/
