Fig 6 OLM Business Component Reference Details for OLM Enrollment Notifications EventDetailsVO
Our goal is to add the Venue Details to the workflow message. Examining each of the VO's, we find that the EnrollmentDetailsVO queries data about the Attendees. The EventDetailsVO returns information about the class. As the Venue is attached to the class and therefore the same for all attendees in the class then the EventDetailsVO is the most appropriate query to add the venue details.
