老师您好！我在调用应收单接口时出现问题：
输入json:
{"Creator":"SCM","NeedUpDateFields":[""],"Model":{ "FID":0,"FBillTypeID":{"FNumber":"YSD01_SYS"},"FBillNo":"SM2016090163","FCUSTOMERID":{"FNumber":"11.02.0000"},"FCURRENCYID":{"FNumber":"PRE001"},"FDATE":"null","F_employee":{"FNumber":"00006"},"FSETTLEORGID":{"FNumber":"001"},"FPAYORGID":{"FNumber":"001"},"FSALEORGID":{"FNumber":"001"},"FSALEDEPTID":{"FNumber":"003"}, "AR_receivable__FsubHeadFinc":{"FExchangeRate":"1"},"FEntityDetail":[{"FEntryID":0,"FMATERIALID":{"FNumber":"FBMH1608HM470-T"},"FPRICEUNITID":{"FNumber":"6667a763086c20427a0a1e703edbcf8e513e"},"FPriceQty":"4500","FBASICUNITQTY":"4500","FPrice":"14.96217231","FEntryTaxRate":17.0,"FEntryDiscountRate":0,"FNoTaxAmountFor_D":"67329.78" },{"FEntryID":0,"FMATERIALID":{"FNumber":"JMK063ABJ105MP-Q"},"FPRICEUNITID":{"FNumber":"6667a763086c20427a0a1e703edbcf8e513e"},"FPriceQty":"3500","FBASICUNITQTY":"3500","FPrice":"3.69000000","FEntryTaxRate":17.0,"FEntryDiscountRate":0,"FNoTaxAmountFor_D":"12915.00" } ]} }
