From an e-Pro webcast listener: Can shared columns be categorized?
Earline asked a question during the webcast that I didn't know the answer to... Can shared columns in ND7 be categorized?
The answer is yes. When you bring in the shared column to your view, just mark it as formula only. Don't bring over the formatting on the shared column. That will allow you access to all the column formatting settings, including the one that controls sorting and categorization.
