Revising an Order

A customer places an order through a call center. The next day, the customer telephones the call center to revise the order, changing the quantity from five items to four items. The call center agent checks the status and sees that the order is still being processed. The agent changes the quantity from five to four.

Another customer places an order and telephones the next day to revise the order, changing the quantity from five items to four items. The call center agent checks the status of the order and sees that it has been shipped. Because it has been shipped, the order record is read-only, and the call center agent cannot change the quantity. The call center agent tells the customer that he cannot change the order because it has already been shipped. Because ordering and fulfillment are integrated, the agent cannot change orders that have already been shipped.
