title: How to evaluate tables/filters in Dax Studio
body: <p>I am wondering is it possible to see in Dax Studio (or other editor) which values are used to filter measure (evaluate expresion that returns table)?
  What I mean by that is I create a measure for example:</p>
  <pre><code>last 3 value = 
  VAR DATES = DATESINPERIOD(calendar[date],LASTDATE(calendar[date]), -3,MONTH)
  RETURN CALCULATE([sum value], DATES)
  </code></pre>
  <p>Now I would like to evalaute this expresion:</p>
  <pre><code>DATESINPERIOD(calendar[date],LASTDATE(calendar[date]), -3,MONTH)
  </code></pre>
  <p>in dax studio to see what values it produces that are later used in filtering.
  I have searched for syntax that would allow it but I have failed. This example measure from above is easy, but I have one thats complicated and having the abillity to see its intermediate steps would help a lot.
  Thanks in advance :)</p>
