As of right now it's IR# 7106084 "NX Multi-Document Environment Enhancement"
Khimani,
You are correct, you can open up multiple files with TeamCenter, but in Native (when we are opening customers data) you don't have that option. I had several files for a customer I needed to look at yesterday and thanks to muscle memory I tried to open them all up at once. Doesn't work. They were all similar parts, but to tell the actual difference in them, instead of using CTRL-TAB to quickly cycle through them, I ended up having to print them all out.
