Pre-Calculating Value Sets for navigational attributes

Has anyone tried creating pre-calculating value sets for navigational attribute?

I tried creating the value set. It let me do it. But when I schedule it for loading, the load crashes with system error.

I was wondering if this is possible at all or not.

When creating value sets in the reporting agent the drop down on the characteristic does show the navigational attributes. So I am not sure why then the scheduling piece of it fails.

Any information to resolve this is greatly appreciated.
