Universe - Context/Object-Question

Hello,

I have some Dimensions A, B, C around different tables in the center, like X, Y, Z.

Now there are Contexts for X, Y and Z-table.

Now my Universe contains now and object like

case

when A.id = 2 then

    '22'

when A.id = 4 then

    case

         when B.id = 3 then

            'D'  

          else

            'E'

      end

   else

      'UNKNOWN' 

end

So tables A, B, and C are not directly join. To join them, I have to use X, Y or Z, depending on the context (and add Table X, Y or Z to the tables-section of the object).

I could create the object for each dimension separately, but I'd like to do a "good" solution.

Thanks in advance

Jens
