Answer:   Scheduled delivery - is a way to batch multiple documents that are acted on (delivered) at scheduled times. When the Deliver Document By processing action indicates a scheduled delivery method, Trading Networks creates a delivery task for the document and places the delivery task in the queue identified with the Deliver Document By processing action. The queue is associated with a schedule and a scheduled delivery service. At the times the schedule indicates, Trading Networks invokes the scheduled delivery service to act on the documents in the queue to deliver them.
