With Ordered Notifications, you typically configure an Integration Server trigger to subscribe to the notification's publishable document and a flow service that the trigger invokes. Because the primary reason to use Ordered Notifications is to preserve the order in which the operations occur, be sure to use the Processing Mode option in Designer when you create the trigger and flow service.

For more information about using configuring Integration Server triggers and flow services, see the webMethods Service Development Help for your release.
