title: Dax measure value constant for all entities
body: <p>If I have a simple table as below</p>
  
  <pre><code>Department    User  Sale
      IT         A      25
      IT         B      25
      DA         C      25
  </code></pre>
  
  <p>Is it possible to create a measure that would keep the sum of <code>sale</code> fixed for each User. So that in a table visual it would appear as:</p>
  
  <pre><code> Department   User  SaleMeasure
      IT         A     50
      IT         B     50
      DA         C     25
  </code></pre>
