title: Descendants (MDX) of root member
body: <p>Environment: SSAS v12.</p>
  
  <p>Why the following function </p>
  
  <p><code>DESCENDANTS([Dim1].[Hier1].[(All)])</code> </p>
  
  <p>returns only <code>[Dim1].[Hier1].[(All)]</code> ?</p>
  
  <p>Expectation is to return the root member and all it's descendants.</p>
  
  <p>Or how to achieve that?</p>
  
  <p>PS Specifying <code>[ , Level_Expression [ ,Desc_Flag ] ]</code> does not help... </p>
  
  <p>Many thanks in advance.</p>
