Cancel an inbound order before any of its shipments arrive at the WFS fulfillment centers.
An inbound order cannot be canceled if any of its shipments have a status of Receiving in Progress, Closed, or Cancelled.
Cancellations are only supported at the inbound order level. If an inbound order is canceled, all shipments within that order are also canceled.
