Order Change
Provides a feature that lets customers change the delivery address and options of an ordered product. Delivery address changes are only possible on the order detail screen, while option changes are possible on both the order list and order detail screens. Changes are only possible when the order history classification code (OM003) is in the Order Completed (11) status, and delivery address changes are only possible between a remote island/mountainous area and a general area.
