Mapping of Dimension based on different data Intersections directly in EPCM Application

Summary:

Dear Experts,

Our Source data is of "No Entity" and we want to map it to proper Entities based on different dimension member combinations (Account → Revenue/ Expense, Customer → All Customer / No Customer, Location → All Location/ No Location, Costcenter → All Costcenter/ No CostCenter, SBA → All SBA/ No SBA). I know we can achieve this easily with the help of Multi Dimension Mappings in Data Management. But are there any alternate options to handle this within EPCM with the help of UDA or Groovy Scripting?

We want to handle this within EPCM Application through metadata (Alternate Hierarchies/ UDAs) which will be managed by EDMCS with no manual interventions.
