通过Web API 保存其它出库单时报错

我通过Web API 保存其它出库时报如下错误，麻烦大神帮忙看看是什么原因引起的，要怎么解决，谢谢！

报错如下：
{"Result":{"ResponseStatus":{"ErrorCode":500,"IsSuccess":false,"Errors":[{"FieldName":"请先录入库存组织(FStockOrgId)的内容（物料编码(FMaterialId)）！","Message":" at Kingdee.BOS.Core.Metadata.FieldElement.BaseDataField.ReadUseOrgId(IDynamicFormModel model, DynamicObject activeRow, String& orgId)\r\n at Kingdee.BOS.Core.Metadata.FieldElement.BaseDataField.BuildQueryParemeter(IDynamicFormModel model, DynamicObject activeRow)\r\n at Kingdee.BOS.Model.DynamicForm.DynamicFormModel.LoadFieldDataWithCoreFilter(BatchBaseDataQueryInputParam queryParam)\r\n at Kingdee.BOS.WebApi.FormService.MapPropertyService.DoBatchBaseFieldNumbers(BaseDataField field, Tuple`2 numberInfos, Int32 rowIndex)\r\n at Kingdee.BOS.WebApi.FormService.MapPropertyService.SetBaseDataField(BaseDataField field, DynamicObject targetObject, Object value, Int32 rowIndex)\r\n at Kingdee.BOS.WebApi.FormService.MapPropertyService.MapComplexProperty(String pkProperty, Dictionary`2 sourceObj, DynamicObject targetObj, Int32 rowIndex, HashSet`1 NeedUpDateFields)\r\n at Kingdee.BOS.WebApi.FormService.MapPropertyService.MapCollectionProperty(Entity enity, IList`1 sourceRows, DynamicObjectCollection targetRows, HashSet`1 NeedUpDateFields, String specialReferenceTable)\r\n at Kingdee.BOS.WebApi.FormService.MapPropertyService.MapComplexProperty(String pkProperty, Dictionary`2 sourceObj, DynamicObject targetObj, Int32 rowIndex, HashSet`1 NeedUpDateFields)\r\n at Kingdee.BOS.WebApi.FormService.Save.Revole()\r\n at Kingdee.BOS.WebApi.FormService.Save.Execute()\r\n at Kingdee.BOS.WebApi.FormService.BillOperationService.ExecuteOperation(FormOperation op, String data)","DIndex":0}],"SuccessEntitys":[],"SuccessMessages":[]}}}

jsonRoot 字符串格式及内容如下：

"FBASEQTY": "2.0000000000",
"FStockId": {
"FNumber": "00019_GZW"
}
}
]
}
}

调用方式如下：
public string OtherOutSave()
{
KDLogin login = new KDLogin();
string result = "";

ApiClient client = login.LoginExt();

if (client != null)
{
DataTable otherIns = DBManager.getDataTableFromDB(" select t3.FNUMBER as FMaterialNumber,t6.FNumber as FUnitNumber, t5.FNUMBER as FStockNumber , sum(t1.FQTY ) as FQty from T_STK_ASSEMBLYSUBITEM t1 left join T_STK_INVENTORY t2 on t1.FMATERIALID = t2.FMATERIALID and t2.FQTY > 0 inner join T_BD_MATERIAL t3 on t3.FMATERIALID = t1.FMATERIALID inner join T_BD_MATERIALBASE t4 on t3.FMATERIALID = t4.FMATERIALID inner join T_BD_Unit t6 on t6.FUnitID = t4.FBASEUNITID left join T_BD_STOCK t5 on t5.FSTOCKID = t1.FSTOCKID where t3.FNUMBER='AA2358X001' group by t3.FNUMBER , t5.FNUMBER , t6.FNumber");

if (otherIns == null || otherIns.Rows.Count <= 0)
{
return "没有查询到可生成其它入库单的数据！";
}

for (int i = 0; i < otherIns.Rows.Count; i++)
{

string jsonRoot;
DataRow dr = otherIns.Rows[i];

jsonRoot = GetOtherOutSaveEntry(dr);

System.Console.WriteLine("=其它入库单保存==" + jsonRoot);

// 调用Web API接口服务
result = client.Execute(
"Kingdee.BOS.WebApi.ServicesStub.DynamicFormService.Save",
new object[] { "STK_MISDELIVERY", jsonRoot });

}
}

return result;
}

【PS：我通过下面的jsonRoot 字符串格式格式保存其它入库单是能够成功的。】
