Filter for one hierarchy and expanding for another one?

Question

Hi to all,
We've a dimension A with 2 different hierarchies (call them as usual PARENTH1 and PARENTH2).
What I've been asked by the users is a little interface, where they can:
- filter for one parent of the first hierarchy
- expand for the parents of the second hierarchy, who share the same base members.
Initially I had hoped that imposing the value desired of the parenth1 in the PageKeyRange, and expanding with a filter like HIR="H2" and HLEVEL="2" would work, but it doesn't work (I get ALL the parents at level 2 of the second hierarchy, not the parents who shares the same basemembers).
Is it possible to model this with an evDRE? If so how? Unfortunately, I cannot make a single hierarchy (this parents aren't in a 1-N relationship between them, unfortunately).
Thank you
Daniele

Hi James,
could you explain more in detail your solution? Because I tried it, and it didn't work as I expected...
Let me explain with an example
Hierarchy1:
Dir_01 has got 4 basemembers (test1, test2, test3, test4), while Dir_02 has got other 2 basemembers (test5, test6)
Hierarchy 2
Es1 has got 3 basemembers (test1, test2, test3), Es2 has got 1 basemember(test4), Es3 has got 2 basemembers (test5, test6)
What I would like to do is to
- filter an evDRE with Dir_01
- "expand" (I believe i've wrongfully explained myself in this point) with the other Hierarchy, which means: I want in the report only the nodes in the hierarchy 2 that share the same basemembers
In this way, I would have as available keys in my evDRE report:
Es1
Es2
With your solution, I even get Es3, which doesn't have any common basemember...
Kind regards
Daniele
