I've seen  quite a few questions on this forum about specifying a default value for a Prompt in a report with Dimensional Package.
Below is a real life example from one of my numerous Cognos projects.
It might give an idea what you can do with a little creativity.
This expression calculates a highest level available for a user in the School Dimension based on the user Security context.
School Dimension levels: Region / Quadrant / Family / School
If a user is a Supervisor of Region A then the expression will return [Region A] member and so on...

Enjoy!
