How can I filter a dimension in MDX Query?

Question

I use SSAS and SQL Server 2008 R2 .

I want select Product that exist inside productcategory that named 'Accessories'.

How I can filter a dimension ?

I write a MDX Query like this :

SELECT 
Filter(
        [Dim Product].[Hierarchy].[ProductCategory] , 
        [Dim Product].[state] =  1
       )
       On Columns
From [Adventure Works DW]

But I got an error :

Executing the query ...
Query (4, 10) The CURRENTMEMBER function expects a hierarchy expression for the 1    
argument. A member expression was used.

Execution complete

There is no need of filtering anything :

SELECT    
  [Dim Product].[Hierarchy].[ProductCategory].[Accessories] On Columns 
From [Adventure Works DW]

[edit] not sure to understand what you want to achieve - how about that - still no need of this Filter function :

SELECT 
  [Dim Product].[Hierarchy].[ProductCategory]  On Columns
From [Adventure Works DW]
where [Dim Product].[state].[1]
