问：如何配置一个销售订单对应多个发货单？
答：这个主要是跟售达方主数据有关。
In your customer master record (in Shipping data, under shipping tab--> Partial deliveries) if the tab Complete Delivery Required by Law is not checked and Partial delivery per item box is blank then you can create any number of partial deliveries.
VD03->Shipping data(Partial deliveries)->Delivery Required AND Partial delivery per item box
