Event Hub overview

The Event Hub is a generic Grid extension for sending events between Infor applications. It is a publisher-subscriber application framework that allows publisher-applications to expose historical data to subscriber-applications that are interested in receiving this data.

In the Event Hub page there are two views for all subscriptions. These views are the Subscriber view that shows the subscriptions as created by the subscribers, and the Publisher view that shows the subscriptions as propagated to the publishers.

EC can act as a subscriber application through the MECEventHubSubscriber channel. You can create multiple MECEventHubSubscriber channels.
