Relations for CV5 Contextual Part

Hello,
I'm looking for a Relation that shows linked objects for CV5 Contextual Part. I mean that I would like to retrieve context (=CATProduct) and import (=CATPart(s)) links to Contextual Part.
With CV5 CCP Part the Relation is "Geometry" and "Geometry of", but not able to find out right relations for CV5 Contextual Part.

Thanks,
Mauro
