I have multiple device groups under a single main group in WUPro...and I can run State Change Timeline reports for each of the lowest level groups.  However, if I try to run a report for the highest group I get no data.

Is this even possible?  The highest group does show up on the web GUI with a radio button, so it's selectable....I just figured all the state changes for all the subgroups/devices would be put together for this report, but I get nothing.

Any ideas??  TIA....

PS:  Are there any data dictionaries available for the SQL db that WUP uses?  Since all the data is in there, if I had to I guess I could do a little report generating on my own....
