We have a db with the following schema:

TableA
TableAB (serves as a many-to-many relationship between A and B)
TableB
TableBC (serves as a many-to-many relationship between B and C)
Table C

The foreign->primary keys are properly set between the tables:
TableA primary key is a foreign key in TableAB
TableB primary key is a foreign key in TableAB
TableB primary key is a foreign key in TableBC
TableC primary key is a foreign key in TableBC

What we want:
To be able to do is show how many C records are related to each A record.

Here is the equivalent sql statement:
select TableA.AKey,count(*)
from TableA,TableAB,TableBC,TableC
where TableA.AKey = TableAB.AKey and
   TableAB.BKey = TableBC.BKey and
   TableBC.CKey = TableC.CKey
group by TableA.AKey

Issuess with SSAS:

We could not create a dimention with a hierarchy of the form A-B-C as it is
not a snowflake schema (not a one-to-many relationship).

We were able to create a many-to-many relation between A as a dimention and
B as a measure table using TableAB as an intermediate measure table but we
could not create a relation between A and C.

What possibilities do we have using SSAS to achieve the equivalent of the
sql statement mentioned above
