title: Need to exclude zero values from SSRS SSDT Report calculations in Field expression window
body: <p>I have Productivity calculation as <strong>TotalMinutes/(TotalHours*60)</strong>
  Some of my TotalHours values=0 and I need to exclude them from calculation.</p>
  
  <p>How do I write it in Field Expression window?</p>
  
  <p>My current expression is 
  (I am also setting zeros to "99" values in this field):</p>
  
  <pre><code>=IIf(Fields!TotalHours.Value=0,99,
   Sum(Fields!TotalMinutes.Value/(Fields!TotalHours.Value*60)))
  </code></pre>
  
  <p>Thank you for help</p>
