title: MDX Running total on every date member
body: <p>I use the following MDX calculation to get the stock value per day:</p>
  
  <pre><code>    SUM({NULL:[Date].[Calendar Hierarchy].CURRENTMEMBER} * [Measures].[Qty])
  </code></pre>
  
  <p>However this is giving me the following result</p>
  
  <p>Date             QtyOnHand</p>
  
  <p>1/1/2015               10</p>
  
  <p>4/1/2015               15</p>
  
  <p>5/1/2015               16</p>
  
  <p>Mark that the dates 2/1/2015 and 3/1/2015 are not shown, because there are no transactions on them.
  I would like to get these  shown to get the following result:</p>
  
  <p>Date             QtyOnHand</p>
  
  <p>1/1/2015               10</p>
  
  <p>2/1/2015               10</p>
  
  <p>3/1/2015               10</p>
  
  <p>4/1/2015               15</p>
  
  <p>5/1/2015               16</p>
  
  <p>How can I adjust my MDX statement to this?</p>
