title: SSRS date filter
body: <p>I have a farely simple tablix:</p>
  
  <pre><code>Year   |  Trimester  |  Measure    
  2016         T1          12    
  2016         T2          8    
  2015         T1          16    
  2015         T2          5    
  2015         T3          8    
  2015         T4          13
  </code></pre>
  
  <p>I'm going nuts trying to come up with a filter which would filter out last year's trimesters that did not yet come to pass this year. Example: I'm at the end of T2 of 2016, so when I generate the tablix, I only want:</p>
  
  <pre><code>Year   |  Trimester  |  Measure   
  2016         T1          12    
  2016         T2          8    
  2015         T1          16    
  2015         T2          5
  </code></pre>
  
  <p>Any ideas? Thanks!</p>
