Total Newbie to boards and OLAP.

A client of ours has an OLAP cube created with various insurance info contained within. I am new to OLAP so need to ask what will be probably a dumb question so apologies in advance.

Is there a way to drill down on a piece of the information contained within the cube to retrieve information that is external from the cube. For instance selecting Claim ID to view info in linked tables (not in the cube)

Any assistance would be greatly appreciated.
