MDX Distinct() not returning unique list of tuples

Question

Environment
Server version 9.2.0.2
BSO database
essmsh client
Behavior
Using Distinct on a Static List of Product members
Distinct( { [ABC], [DEF], [ABC], [GHI] } )
results in
{ [ABC], [DEF], [GHI] }
as I expected.
In a hierarchy where ABC and DEF are also shared members in alternate hierarchies
[Product].levels(0).Members
results in
{ [ABC], [DEF], [ABC*], [DEF*], [GHI] }
where the (*) members are the shared instances.
Applying the Distinct function
Distinct( [Product].levels(0).Members )
results in
{ [ABC], [DEF], [ABC*], [DEF*], [GHI] }
which is NOT what I expected.
Q1) Any insight as to why Distinct is behaving in this fashion?
Q2) How can I get a unique list of members from a function that returns a set of non-unique tuples?
Thanks in advance.

Hi,
Are you telling that filterdup is case sensitive ? if that is your problem why not try downase / upcase while
storing to the list and then try filterdup.
