My aim is to get filtered member list including its properties from specific hierarchy. It's critical because of huge hierarchy.
I found two slow way:
What the way EXCEL, BIDS or any other viewer handles that?
I found out the answer simply by debugging the action in SQL Server Profiler, I was sure there was some function within AMO library. It uses MDX query, i.e.:
SELECT SUBSET( FILTER( ADDCALCULATEDMEMBERS( [Client].[Code].[All clients].CHILDREN ), ( INSTR( [Client].[Code].CurrentMember.Name, "999" ) > 0 ) ), 0, 1001 ) DIMENSION PROPERTIES MEMBER_NAME, MEMBER_TYPE ON 0, {} ON 1 FROM [MyCube]
