Do we have a way to track which of the UDT members are being used, and which arent used. I saw that Tag Diagnsotics is supposed to let oyu do something similar for tags, but I want to clean up my UDTs instead. Also the tag reference tool doesnt let you work for embedded views so I can't really cross reference the UDT members being passed on to a view as all of them are (im using a dynamic tag path that i propogate through my views and faceplates)
If you want you can use the tag report tool in script form, search for
Types: UDT Instance
Add a criteria of Parent Data Type = 'YourUDTName'
Then you can just build a list of the UDT Types you want to search for, loop and append the results to a dataset.
Tag Report Tool and Tag Reference Tracker are distinctly different things. It sound like you are asking about the reference tracker, not the report tool?
