订单中第一个产品的交货费您想显示最高“产品价值”的“交货费”吗？您能添加代码吗？如何知道要退回或不退回哪个交货费？老实说，产品价值在OrderID之后按降序排列完全是巧合。每份订单的标准送货费为3.50英镑。因此，当我运行报告时，我只想显示orderHello中第一个产品的交付费用，谢谢您的回复。不幸的是，这对我来说是行不通的，因为有多个产品具有相同的单位成本。在实现此排名功能后，尽管在某些情况下可以正常工作，但仍有许多订单将交货费用分配给多个产品。还有别的办法吗？@MattJA你已经接受了一个合适的解决方案。要点与我的建议相同，它只是计算每个分区中的记录，而不是根据

productValue
