Actually I have a mistake in my original request. The CallTypes Business Objects Groups contains approx 20 Business Objects. Each Object has an attribute of CallRecord and Event. There is only one type of Call Record Object, however the Event attribute can be any one of the twenty Call Types Business Objects. There is an attribute of Status on Callrecord but also an attribute of Status on each object in the EVENT attribute.
Therefore I can do a search direct on Call Record for Status however the Event.Status can be in any number of business objects.
I actually need to find all EVENTS where status - Open
