Acumatica 试图通过Web API在销售订单中添加“折扣详细信息”时出现“类型可能不为空”错误

我尝试通过web API添加带有预设折扣代码的销售订单，代码如下：

        SO301000Content SO301000 = context.SO301000GetSchema();
        context.SO301000Clear();

        List<Command> cmds = new List<Command>();


        cmds.Add(new Value { Value = "SO", LinkedCommand = SO301000.OrderSummary.OrderType });
        cmds.Add(new Value { Value = "<NEW>", LinkedCommand = SO301000.OrderSummary.OrderNbr });
        cmds.Add(new Value { Value = orderInfo.OrderCustomerInfo.AcctCD, LinkedCommand = SO301000.OrderSummary.Customer });
        cmds.Add(new Value { Value = orderInfo.OrderLocationInfo.ID, LinkedCommand = SO301000.OrderSummary.Location });

        cmds.Add(new Value { Value = orderInfo.ShippingTotal.ToString(), LinkedCommand = SO301000.Totals.PremiumFreight });

        cmds.Add(new Value { Value = "N30", LinkedCommand = SO301000.FinancialSettingsFinancialInformation.Terms});


        cmds.Add(new Value { Value = orderInfo.OrderNumber, LinkedCommand = SO301000.OrderSummary.ExternalReference });

        if (orderInfo.ShippingTotal > 0) { 
            cmds.Add(new Value { Value = orderInfo.ShippingTotal.ToString(), LinkedCommand = SO301000.Totals.PremiumFreight });
            cmds.Add(new Value { Value = orderInfo.ShippingTaxCategory, LinkedCommand = SO301000.Totals.FreightTaxCategory });
        }

        if (!string.IsNullOrEmpty(orderInfo.PromoCode))
        {
            cmds.Add(SO301000.DiscountDetails.ServiceCommands.NewRow);
            cmds.Add(new Value { Value = orderInfo.PromoCode, LinkedCommand = SO301000.DiscountDetails.DiscountCode });
            cmds.Add(new Value { Value = "000", LinkedCommand = SO301000.DiscountDetails.SequenceID });
            cmds.Add(new Value { Value = "Group", LinkedCommand = SO301000.DiscountDetails.Type });
            cmds.Add(new Value { Value = orderInfo.OrderQty.ToString(), LinkedCommand = SO301000.DiscountDetails.DiscountableQty });
        }



        //add line items
        foreach (OrderItem item in orderInfo.OrderItems)
        {
            cmds.Add(SO301000.DocumentDetails.ServiceCommands.NewRow);
            cmds.Add(new Value { Value = item.InventoryCD, LinkedCommand = SO301000.DocumentDetails.InventoryID });
            cmds.Add(new Value { Value = item.Quantity.ToString(), LinkedCommand = SO301000.DocumentDetails.Quantity });
            cmds.Add(new Value { Value = "Server", LinkedCommand = SO301000.DocumentDetails.Warehouse });


            cmds.Add(new Value { Value = "True", LinkedCommand = SO301000.DocumentDetails.ManualDiscount});

            if (item.DiscountPercent > 0)
            {
                cmds.Add(new Value { Value = item.DiscountPercent.ToString(), LinkedCommand = SO301000.DocumentDetails.DiscountPercent, Commit = true });
            }
            else if (item.DiscountAmount > 0)
            {
                cmds.Add(new Value { Value = item.DiscountAmount.ToString(), LinkedCommand = SO301000.DocumentDetails.DiscountAmount, Commit = true });
            }

        }

        cmds.Add(SO301000.Actions.Save);
        cmds.Add(SO301000.OrderSummary.OrderNbr);
        cmds.Add(SO301000.OrderSummary.OrderTotal);
        cmds.Add(SO301000.OrderSummary.TaxTotal);
        cmds.Add(SO301000.OrderSummary.Location);
        cmds.Add(SO301000.OrderSummary.Customer);

        SO301000Content[] SO30100content = context.SO301000Submit(cmds.ToArray());

然而，我得到的错误如下：

PX.Data.PXException:错误12:插入“销售订单折扣明细”记录引发了一个或多个错误。请复习。错误：“类型”不能为空。-->PX.Data.PXOuterException:错误12:插入“销售订单折扣明细”记录引发了一个或多个错误。请复习

您可以在我的代码中看到，我显式地将组分配给了SO301000.DiscountDetails.Type，这与设置的折扣代码完全相同-我不明白为什么仍然出现错误

谢谢。

好的。我想出来了-原来添加折扣详细信息代码应该放在添加行项目的代码之后，即我的代码应该更改为：

   ..........

   //add line items
    foreach (OrderItem item in orderInfo.OrderItems)
    {
        cmds.Add(SO301000.DocumentDetails.ServiceCommands.NewRow);
        cmds.Add(new Value { Value = item.InventoryCD, LinkedCommand = SO301000.DocumentDetails.InventoryID });
        cmds.Add(new Value { Value = item.Quantity.ToString(), LinkedCommand = SO301000.DocumentDetails.Quantity });
        cmds.Add(new Value { Value = "Server", LinkedCommand = SO301000.DocumentDetails.Warehouse });


        cmds.Add(new Value { Value = "True", LinkedCommand = SO301000.DocumentDetails.ManualDiscount});

        if (item.DiscountPercent > 0)
        {
            cmds.Add(new Value { Value = item.DiscountPercent.ToString(), LinkedCommand = SO301000.DocumentDetails.DiscountPercent, Commit = true });
        }
        else if (item.DiscountAmount > 0)
        {
            cmds.Add(new Value { Value = item.DiscountAmount.ToString(), LinkedCommand = SO301000.DocumentDetails.DiscountAmount, Commit = true });
        }

    }


    .........

  //add discount details if there is promo code being used in sales order
  if (!string.IsNullOrEmpty(orderInfo.PromoCode))
    {
        cmds.Add(SO301000.DiscountDetails.ServiceCommands.NewRow);
        cmds.Add(new Value { Value = orderInfo.PromoCode, LinkedCommand = SO301000.DiscountDetails.DiscountCode });
        cmds.Add(new Value { Value = "000", LinkedCommand = SO301000.DiscountDetails.SequenceID });
        cmds.Add(new Value { Value = "Group", LinkedCommand = SO301000.DiscountDetails.Type });
        cmds.Add(new Value { Value = orderInfo.OrderQty.ToString(), LinkedCommand = SO301000.DiscountDetails.DiscountableQty });
    }

    cmds.Add(SO301000.Actions.Save);

   ........

在设置类型的值后，尝试添加commit=true。还尝试在UI中复制相同的场景。@Hybridzz，commit=true不起作用。但同样的过程在UI中也能工作。有人能帮忙吗？我尝试了所有不同的方法，但都没有成功@加布里埃尔，你能花点时间看看我的问题并帮我一下吗？
