title: SSAS Date Measure Max StringFormat when Null
body: <p>I have a cube with a measure of type date, performing a max aggregation, where some of the data points have a null value for date. In these cases, the Max value becomes 12/30/1899 which I believe is the earliest expression of a date. </p>
  
  <p>Is there a way to have these appear in the results as blank rather than this bogus date?</p>
  
  <p>I tried to use the measure's StringFormat property with no luck.</p>
