Edited my original response...
In this case, ICAD intentionally does not issue CAD Listener messages when a closed event is modified/updated. So therefore IFCAD never hears about it, and it doesn't get sent to the CCEF (CAD Connect) System.
We're trying to think about whether there are any possible “workarounds”/”customizations” to do what you would like to do. One idea is to maybe set up a database trigger that would catch situations like this, and the action for that trigger could do something that EdgeFrontier is able to detect (like send an message over TCP). Then within EF they could request the IFCADEventReport for the report.
