How do you derive properties in list, from a list, between two different dimensions?

Summary:

For example, I have property X in dimension A, which is a list, that has values 123456789,378654728. I would like to return via a derivation in property Y, in dimension A, the descriptions of each of these properties (ie. Credit Cards, Debit Cards), where the descripiton for these values is held in dimension B.
