Specifies the object that contains the event publisher function that the event subscriber responds to.
This property is only available when the Event Property is set to Subscriber.
You use this property to set up an event subscriber function to subscribe to a published event. There are three types of events: business, integration, and trigger.
Business and integration events are published by event publisher functions in objects such as codeunits, pages, or tables. To subscribe to a business or integration type event, you specify the object that contains the event publisher function for the event.
Trigger events are system events that are declared in tables. To subscribe to a trigger event, you specify the table.
After you set this property, you set the EventFunction Property to specify the event publisher function that you want the event subscriber to subscribe to.
