title: Qlikview - Target missing where no actual value
body: <p>I have a <strong>fact</strong> table of <code>Delay</code> by <code>Date</code> by <code>Category</code> (and many other Fields). I have another (<strong>target</strong>) table of <code>DelayTarget</code> by <code>Month</code> and <code>Category</code>. </p>
  
  <p>I am currently associating the target table to the fact table on <code>Month &amp; Category</code> but when there is no <code>Delay</code> for a given <code>Category</code> in a given <code>Month</code>, then the <code>DelayTarget</code> value does not display in my dashboard.</p>
  
  <p>How do I associate the <code>DelayTarget</code> to all <code>Months</code> in my main dataset - even when there is no <code>Delay</code> to report? I think I want to create a Zero value for <code>Delay</code> when it is null but I don't know how to do this or if this is the best method.</p>
