无法正确保存qb在线发票

Question

我可以在线购买quickbook上的发票，但是当我在线检查quickbook发票时，它会创建项目列表，但缺少价格和说明。我做错了什么。

          invoice.AlternateId = new NameValue[] { new NameValue() { Name = "InvoiceID", Value = service.InvoiceId } };

                InvoiceHeader Header = new InvoiceHeader();
                Header.DocNumber = service.InvoiceId;
                Header.TxnDate = service.ServiceDate;
                Header.TxnDateSpecified = true;
                Header.Msg = service.Note.ToString();
                Header.Note = service.Note.ToString();

                Header.CustomerId = new IdType() { idDomain = idDomainEnum.QBO, Value = service.CustomerNumberOnline };
                Header.Currency = currencyCode.USD;
                Header.ShipDate = service.ServiceDate;
                Header.ShipDateSpecified = true;


                //Print and Email Option fields
                if (EmailPrintOption == "Both")
                {
                    Header.ToBeEmailed = true;
                    Header.ToBeEmailedSpecified = true;
                    Header.ToBePrinted = true;
                    Header.ToBePrintedSpecified = true;
                }

                {
                    Header.ToBeEmailed = false;
                    Header.ToBeEmailedSpecified = false;
                    Header.ToBePrinted = false;
                    Header.ToBePrintedSpecified = false;

                }

                PhysicalAddress BillAddress = new PhysicalAddress();

                BillAddress.PostalCode = service.SoldToZip;
                BillAddress.Tag = new string[] { "Billing" };
                Header.BillAddr = BillAddress;

                PhysicalAddress ShipAddress = new PhysicalAddress();
                ShipAddress.Line1 = service.JobJocationAddress;
                ShipAddress.City = service.JobLocationCity;
                ShipAddress.CountrySubDivisionCode = service.JobLocationState;
                ShipAddress.PostalCode = service.JobLocationZip;
                BillAddress.Tag = new string[] { "Shipping" };
                Header.ShipAddr = ShipAddress;

                decimal discount;
                if (decimal.TryParse(service.Discount, out discount))
                {

                    Header.Item = -1 * discount;  //discount must be negative
                }

                for (int i = 0; i < InvoiceLines.Length; i++)
                {
                    InvoiceLines[i] = new InvoiceLine();
                    InvoiceLines[i].ItemsElementName = new Intuit.Ipp.Data.Qbo.ItemsChoiceType2[]
                            {

                    };
                }
                invoice.Line = InvoiceLines; 

                Header.SalesTermName = service.PaymentType;
                Header.SalesRepName = service.TechName;
                Header.PONumber = service.PurchaseOrder;
                invoice.Header = Header;

我想念的是什么？ 这里发生的是，当我将发票行添加到发票时，它将每个项目的金额设置为＆＃34; 0＆＃34;默认情况下，所以当我尝试以实际方式添加折扣时，它会给出折扣误差大于小计的错误。但我的问题是，为什么我需要在我之前已经定义它们时明确地为每个项目增加成本。我们应该只添加itemId，其余的QB应该计算。
