我正在运行Magento 1.5.1.0，过去在发票总额的税务计算方面遇到问题。虽然我的商店中的所有总额的计算都是正确的，但后端发票视图和pdf发票会显示不正确的总额。
错误的显示值和正确的值之间的差异可以在这张图片上看到：（简短版本：小计将包括运输税，尽管运输税已经包含在运输中）http://i731.photobucket.com/albums/ww318/vitamin6/orderview_fixed.jpg
所以我在freestyle.com上发布了这个问题，有人设法解决了它。但正如我后来发现的那样，这个解决方案并不能涵盖所有情况——如果订单是免费送货的，发票小计仍然不正确。以下是显示差异的屏幕截图：http://i731.photobucket.com/albums/ww318/vitamin6/orderview_freeship.jpg
自由职业者编辑了以下文件以修复错误的税务计算：app''code''local''Mage''Sales''Model''Order''Invoice''Total''Subtotal.php
在那里有以下代码：
if ($invoice->isLast()) {
$subtotal = $allowedSubtotal;
$baseSubtotal = $baseAllowedSubtotal;
$subtotalInclTax = $allowedSubtotalInclTax;
$baseSubtotalInclTax = $baseAllowedSubtotalInclTax;
被替换为：
if ($invoice->isLast()) {
$subtotal = $allowedSubtotal;
$baseSubtotal = $baseAllowedSubtotal;
//$subtotalInclTax = $allowedSubtotalInclTax;
//$baseSubtotalInclTax = $baseAllowedSubtotalInclTax;
$subtotalInclTax = min($allowedSubtotalInclTax, $subtotalInclTax);
$baseSubtotalInclTax = min($baseAllowedSubtotalInclTax, $baseSubtotalInclTax);
有人能给我指一个正确的方向吗？我必须如何进一步修改文件，以使免费送货的订单能够修复？如果需要，可以提供有关税务设置等的更多详细信息-提前感谢！
汇总排序有一个错误，可能会导致非常严重的问题。
您有添加总计的模块吗？

这是很久以前的事了，对我来说，这个问题通过一个magento更新得到了解决（我现在使用的是1.8.1.0）。我浏览了我的旧文件，我能找到的只有这个编辑：
