title: MDX Except function in where clause
body: <p>I'm having problem restricting a query in mdx, using except function at where clause. i need to retrieved a set of data but which not in an specific set. Then i created the next query:</p>
  
  <pre><code>select {[Measures].[Amount], [Measures].[Transaction Cost], [Measures].[Transaction Number]} ON COLUMNS,{[ManualProcessing].[All ManualProcessings].[MAGNETICSTRIPE], ManualProcessing].[All ManualProcessings].[MANUAL]} ON ROWS 
  FROM [Transactions]
  where except([Product].[All Products].Children,{[Product].[All Products].[Debit})
  </code></pre>
  
  <p>apparently this works fine, but when I try to add another restriction to slicer, I got this error: No function matches signature (Set,Member).</p>
  
  <p>I'm currently working on mondrian 3.1</p>
  
  <p>Is it possible to add multiple restriction to slicer when im sing the except function ? 
  are there any other way to get this ?</p>
