参考这个：获取单据体的DynamicObjectCollection ，然后创建行，附加到单据体集合中，保存就行

FormMetadata meta = MetaDataServiceHelper.Load(ctx, "TLJE_StoreReceive") as FormMetadata;

//创建单据

DynamicObject bill = meta.BusinessInfo.GetDynamicObjectType().CreateInstance() as DynamicObject;

//或抓现有单据数据包

DynamicObject bill = BusinessDataServiceHelper.LoadSingle(this.Context, Id,meta.BusinessInfo.GetDynamicObjectType());

bill[""]=xxx;//单据头赋值

DynamicObjectCollection saleCol = bill["TLJE_StoreEntry"] as DynamicObjectCollection;//取单据体

//如果需要修改原有数据，直接

foreach(DynamicObject entry in saleCol)

{

entry[""]= XXX ;

}

//如果需要新增单据体行

saleCol.Clear();//清空原有数据，如果要保留原数据，得去掉

DynamicObject saleEntry = null;

saleEntry = saleCol.DynamicCollectionItemPropertyType.CreateInstance() as DynamicObject;//创建单据体行

saleEntry[""]=xxx; //赋值

saleCol.Add(saleEntry);//附加行

//调用保存

OperateOption saveOption = OperateOption.Create();

saveOption.SetVariableValue("IgnoreWarning", true);

saveOption.SetVariableValue("_IgnoreInteraction_", true);

IOperationResult save = BusinessDataServiceHelper.Save(this.Context, meta.BusinessInfo, bill, saveOption);

if (save.IsSuccess)

{//保存成功

}
