Filtered Value List that Excludes Portal Values
Anyone know how to create a filtered value list that excludes values that have already been selected?
Here's the context... A Meeting TOG includes Attendees and People, as shown in screenshot.
The Meeting layout has a portal to the Attendees, and the portal contains a popup of People.
I'd like the popup to show all the People records, except those that are already in the portal.
I've tried several filters, but I'm stumped.
