If you're back again someday Wayne, I'm setting this up now on our site. Creo 2 M120, WC 10.1. I'll post results here.
Thanks for the reminder. I did NOT get it to work with Creo 2 M120, WC 10.1 M010. But PTC Support reported to me they did with Creo 3.0 M040, Windchill 10.2 M030.
I came across this after I posted. It was fixed in M140. I am working on M150 but it still won't work fully. I get the Search button but it doesn't return anything. I have a call into PTC about it.
