title: How to use MDX Filter function to exclude specific members by Name
body: <p>I need an MDX query to show several sets of data with a filter to exclude certain ID numbers.
  For example,  this query will INCLUDE only one ID number</p>
  
  <pre><code>SELECT [Measures].[Gross Amt] ON COLUMNS,
  FILTER( 
     [Policy].[Policy Name].[Policy Name]
  *  [Policy].[Policy ID].[Policy ID],
  [Policy].[Policy ID].Name = "622743"
  )
  ON ROWS
  FROM EXPOSURE
  </code></pre>
  
  <p>What I want to do is EXLUDE a group of ID's like this</p>
  
  <pre><code>SELECT [Measures].[Gross GAAP Par OS Amt] ON COLUMNS,
  FILTER( 
     [Policy].[Policy Name].[Policy Name]
  *  [Policy].[Policy ID].[Policy ID],
  [Policy].[Policy ID].Name 
      ****NOT IN [PolicyB].[Policy ID].AllMembers****
  )
  ON ROWS
  FROM EXPOSURE
  </code></pre>
  
  <p>What is the correct syntax to exlude the members of PolicyB ?</p>
