Entering shipping information
The Ship to Info tab is used to designate a Ship to customer when an order's Ship to and Bill to customer differ. You also can use the Ship to Info tab to edit a customer's name and address information for an individual order.
By default, the Ship to Info tab displays the Bill to customer's name and address information. When an ID other than the Bill to customer's ID is entered in the ID field, the Ship to customer's name and address information automatically populate the tab.
If necessary, a customer's name and address information can be edited for an order regardless of whether the Bill to and Ship to customer are the same. Changes made to a Ship to customer's name and address information on the Ship to Info tab affect only the order you are editing; updates made on the Ship to Info tab do not affect a customer's record.
