采购入库单，更新实收数量，接口成功，数据没变

传参
{ \"Creator\": \"whm\", \"NeedUpDateFields\": [\"FRealQty\",\"FDate\"], \"Model\": { \"FID\": 101345, \"FBillTypeID\": { \"FBILLTYPEID\": \"STK_InStock\" }, \"FBusinessType\": \"CG\", \"FStockOrgId\": { \"FOrgID\": 1 }, \"FPurchaseOrgId\": { \"FOrgID\": 1 }, \"FSupplierId\": { \"FSupplierId\": 216385 }, \"FDate\":\"2016-08-29\", \"STK_InStock__FInStockEntry\": [ { \"FMaterialId\": 231567, \"FUnitID\": 10101, \"FStockID\": 231454, \"FStockLocID\": 0, \"FStockStatusId\": 10000, \"FRealQty\": 30.0 } ] }}
接口返回
{"Result":{"ResponseStatus":{"IsSuccess":true,"SuccessEntitys":[{"Id":101345,"Number":"CGRK01307","DIndex":0}]},"Id":101345,"Number":"CGRK01307"}}
