The Publication event is the root event and the parent event for all of the subscription events that

Cloud Integration Hub

generates during processing. After the published data is ready for subscribers,

Cloud Integration Hub

generates a Subscription child event for each subscriber that needs to consume the published data. The Publication event contains aggregated status information for all Subscription child events.

By default, the

Events

page displays root events: Publication, File, Aggregated Subscription, and Compound Subscription. After a publication is ready for subscribers, you can drill down to the associated Subscription child events of the publication.
