Question

我在销售订单屏幕上有Acumatica的自定义代码，如果有人覆盖了默认的送货地址，那么它也会将税区覆盖到被覆盖的送货地址中提供的邮政编码。但是，当税区应该是我们已添加到税区的免税时，它不应该覆盖此税区。这是我的代码：

  namespace PX.Objects.SO
{
  public class SOOrderEntry_Extension : PXGraphExtension<SOOrderEntry>
  {
    #region Event Handlers
private bool setCustomTaxZoneID = false;
        protected void SOShippingAddress_PostalCode_FieldUpdated(PXCache sender, PXFieldUpdatedEventArgs e,
            PXFieldUpdated del)
        {
            SOShippingAddress row = e.Row as SOShippingAddress;
            if (row != null && sender.Locate(row) != null && 
                row.OverrideAddress == true && !string.IsNullOrEmpty(row.PostalCode))
            {
                var order = Base.Document.Current;
                order.OverrideTaxZone = true;
                setCustomTaxZoneID = true;

            }

            try
            {
                if (del != null)
                {
                    del(sender, e);
                }
            }
            finally
            {
                setCustomTaxZoneID = false;
            }
        }

        protected void SOOrder_TaxZoneID_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e,
            PXFieldDefaulting del)
        {
            SOOrder row = e.Row as SOOrder;
            if (row != null && setCustomTaxZoneID && row.OverrideTaxZone == true)
            {
                var shippingAddress = (SOShippingAddress)Base.Shipping_Address.Select();
                var location = (SOOrder)Base.CurrentDocument.Select();
                if (!string.IsNullOrEmpty(shippingAddress.PostalCode))
                {

                    var taxZoneZip = PXSelect<TaxZoneZip,
                        Where<TaxZoneZip.zipCode, Equal<Required<TaxZoneZip.zipCode>>>>
                        .Select(Base, shippingAddress.PostalCode)
                        .RowCast<TaxZoneZip>().OrderBy(z => z.TaxZoneID).FirstOrDefault();
                  var cust = PXSelect<Location, Where<Location.bAccountID, Equal<Current<SOOrder.customerID>>>>.Select(Base, location.TaxZoneID);
                    if (taxZoneZip != null && cust != "EXEMPT")
                    {
                        e.NewValue = taxZoneZip.TaxZoneID;
                    }
                }
                return;
            }

            if (del != null)
            {
                del(sender, e);
            }
        }

    #endregion
  }
}

我得到的错误是：

Building directory '\WebSiteValidationDomain\App_RuntimeCode\'.
\App_RuntimeCode\SOOrderEntry.cs(92): error CS0019: Operator '!=' cannot be applied to operands of type 'PX.Data.PXResultset<PX.Objects.CR.Location>' and 'string'
\App_RuntimeCode\SOOrderEntry.cs(92): error CS0019: Operator '!=' cannot be applied to operands of type 'PX.Data.PXResultset<PX.Objects.CR.Location>' and 'string'

Answer 1

我们认为，当您将Operator '!=' cannot be applied to operands of type 'PX.Data.PXResultset<PX.Objects.CR.Location>' and 'string'变量与cust字符串常量进行比较时，会生成错误"EXEMPT"：

if (taxZoneZip != null && cust != "EXEMPT")
{
    ...
}

可能你应该将一些taxZoneZip字段值与字符串常量进行比较，如下所示：

taxZoneZip.TaxZoneID != "EXEMPT"

税区豁免覆盖
