I need to create a cross-reference table mapping a user-entered code to a combination of two finance dimensions selected from dropdown lists. I can create IDO's from data lake objects that represent each of these dimensions and their descriptions. Is it possible to use these as Domain IDOs for Property Classes, and use those Property Classes for the dropdown lists? I've also considered API calls in the FSM suite, but architecturally I'm wondering if these options are even possible, or if lookups need to be static reference data stored in internal tables.
