title: MDX - how to exclude certain members in mdx
body: <p>i'm wondering how to exclude certain members from one dimension that have links with other members from another dimension ... let's say i want to exclude clients (dim_clients) that have a status A OR a status B (dim_status).
  I know how to crossjoin the two dimensions to obtain those clients but i can't figure out how to exclude them from my calculation since the EXCEPT function accepts two sets from same dimensionality but the ones i want to exclude are the result of a crossjoin operation, i can't use the except function</p>
  
  <p>i want something like this :</p>
  
  <pre><code>SELECT Measure.MyMeasure ON 0 
  FROM MyCUBE 
  WHERE 
  EXCEPT([DIM CLIENTS].[Clients], [EXCLUDED CLIENTS])
  </code></pre>
  
  <p>Thanks</p>
