title: MDX ParallelPeriod CurrentMember
body: <p>I want to select <code>[paid amt]</code> of "2006 Quarter 1" and the <code>ParallelPeriod</code> which is "2005 Quarter 1". My query is below:</p>
  
  <pre><code>WITH
  
  MEMBER [Measures].[ParallelPeriod Qtr] AS 
  PARALLELPERIOD( [Svc Date].[Svc Date].[Svc Qtr], 4, [Svc Date].[Svc Date].CURRENTMEMBER )
  
  SELECT  
  NON EMPTY 
  { [Measures].[Pd Amt], [Measures].[ParallelPeriod Qtr] } 
  ON COLUMNS, 
  NON EMPTY 
  {
  [Svc Date].[Svc Date].[Svc Qtr].&amp;[20061]
  } 
  ON ROWS 
  
  FROM [health costings model]   
  </code></pre>
  
  <p>But the <code>[Measures].[ParallelPeriod Qtr]</code> doesn't return the value. </p>
  
  <p>Does anyone know what is wrong with my MDX query? Or is there any other way to generate Period over Period Variance. Thanks a lot!</p>
