return shipping order

基本解释

The return shipping will be refunded only if we have made a mistake on your order, which would include sending you defective items.
这句是不是说如果对方发货时有错误（包括发送了有瑕疵的货物），那么退货的运费由对方承担呢？
The return structure OrderInfo contains the order number (which is used for tracking), the shipping costs, and shipping address information.
返回的结构 OrderInfo包含订单 ID 号（用作跟踪）、送货成本和送货地址信息。
As with movement type 502, a return delivery to the vendor is entered without reference to the purchase order, but the goods issue is posted via a delivery in Shipping.
正如移动类型502一样，可以不带参考采购订单地输入一个退货交货（单）给供应商，但发货时要通过交货单来过帐。
