在销售订单屏幕中更改运费税类别不会重新计算运费税

Question

我正在根据详细信息标签中所选项目的税种来实际更改货运税种

protected virtual void SOOrder_CustomerLocationID_FieldUpdated(PXCache sender, PXFieldUpdatedEventArgs e, PXFieldUpdated del)
    {
        if (del != null)
            del(sender, e);
        var row = (SOOrder)e.Row;
        Location location = PXSelect<Location, Where<Location.locationID, Equal<Required<Location.locationID>>>>.Select(Base, Base.Document.Current.CustomerLocationID);
        if (location != null)
        {
            string custtaxzone = location.CTaxZoneID;
            bool taxableitem = false;
            if (custtaxzone == "TAXABLE")
            {
                foreach (SOLine line in Base.Transactions.Select())
                {
                    if (line.TaxCategoryID == "PATAX")
                    {
                        taxableitem = true;
                        break;
                    }
                }
                if (taxableitem)
                    Base.Document.Current.FreightTaxCategoryID = "PATAX";
                else
                    Base.Document.Current.FreightTaxCategoryID = null;
            }
        }
    }

该值已正确更新，但未计算运费税。

在RowUpdated事件中，更改值后更新DataView并调用tax属性的计算：

FormData

调用默认属性以清除运费税：

public void SOOrder_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)
{
   SOOrder row = e.Row as SOOrder;

   if (!sender.ObjectsEqual<SOOrder.customerLocationID, SOOrder.customerLocationID>(e.OldRow, e.Row))
   {        
      Base.Document.Current.FreightTaxCategoryID = "PATAX";
      Base.Document.Update(Document.Current);
      SOOrderTaxAttribute.Calculate<SOOrder.freightTaxCategoryID>(sender, e);
   }
}
