是否可以部分退款来退税？

8

在发出贷项通知单（也称为退款）时，Magento会自动退还运输和产品税，但不退还在“调整退款”字段中输入的值（也称为部分退款）。

是否可以配置Magento，使其对调整退款字段中输入的值自动退税？

您将在该类中找到处理此问题的代码Mage_Sales_Model_Order_Creditmemo_Total_Tax。

该行代码$part = $creditmemo->getShippingAmount()/$orderShippingAmount;（位于第116行）清楚地表明，这是经过专门编码的，仅用于根据creditMemo表单中的shippingAmount字段计算税款。

明显的变化是将代码调整为也使用“调整退款”字段。

由于magento如何在creditmemo计算中将其实例化为Totals Collector子系统的一部分，因此您实际上无法重写此类。

但是，您可以调整收集器以使用您自己的类的版本，因此不会丢失所有内容。

因此，在您自己的模块中，将以下代码放置在config.xml中。它进入<global>元素内部

<global>
    <sales>
      <order_creditmemo>
         <totals>
            <tax>
              <class>NAMESPACE_MODULE/order_creditmemo_total_tax</class>
              <after>subtotal</after>
            </tax>
         </totals>
      </order_creditmemo>
   </sales>
<global>

现在，您将创建类文件NAMESPACE/MODULE/Model/Order/Creditmemo/Total/Tax，该文件扩展了核心文件。

class NAMESPACE_MODULE_Model_Order_Creditmemo_Total_Tax extends Mage_Sales_Model_Order_Creditmemo_Total_Tax

您将需要将核心类的整个`collect'方法复制到新文件中。

在第114行添加以下代码（紧随该代码之后$shippingDelta = $baseOrderShippingAmount - $baseOrderShippingRefundedAmount）

 /** adjust to also calculate tax on the adjustment value **/
            $adjustment = ($creditmemo->getAdjustment() > 0)?$creditmemo->getAdjustment():$creditmemo->getShippingAmount();
            if($creditmemo->getAdjustment() > 0 && $creditmemo->getShippingAmount() > 0) {
                $adjustment = $creditmemo->getAdjustment() + $creditmemo->getShippingAmount();
            }
            /** end adjustment **/

并将线116从调整$part = $creditmemo->getShippingAmount()/$orderShippingAmount;为$part = $adjustment/$orderShippingAmount;

然后，这将有效地在计算中使用“装运金额”或“调整金额”。

谢谢！但是，如果我理解正确，那么这仅在存在运输成本的情况下有效。没有运费将无法正常工作。

实质性的问题是，magento不知道要使用哪个税收因素。如果没有可退款的产品，则没有税率。

我只是使用我可以在产品中找到的最高税率来解决此问题，请随时根据您的用例进行调整。

该税是在课程结束时在calculateTaxForRefundAdjustment中计算的。

我可以确认这比最近的Magento版本（1.9.xx）可接受的答案更好。
— 大安范登伯格
@Fabian，您的解决方案很好，但是为什么要更新贷项凭证小计？，好像我不退还任何产品和运费，而是通过“调整退款”退款了一些金额，那么它显示了从调整退款金额到小计的税额。
— Yogita
没有。该代码不包含“小计”
— Fabian Blechschmidt
@FabianBlechschmidt，您是对的，该代码不包含小计，但我的使用方式-我没有退还运费或物品，因此我的小计最初为$ 0.00，我仅退款“ Adjustment Refund”。贷项凭单生成后，当我打开该视图以查看时，它将以小计显示税额，但小计应为零，因为我没有退还任何项目。我的系统包括 税和我退还$ 10.00的裁决退款（$ 0.65税）。然后向我显示小计= $ 0.65调整退款= $ 10.00总计Incl。不含税= $ 10.00不含税= $ 0.65 税费= $ 9.35为什么小计为零？
— Yogita
请打开一个新问题，描述您做了什么，发生了什么以及期望得到什么。

由于明天缺少回复且赏金到期，因此我的解决方法如下：

输入Adjustment Refund含税的。

请注意注释中的细分，以供您参考和供客户参考。
