title: SSAS - Category Dimension - Unknown Member
body: <p>I have an issue with getting my dimension set up properly.  Basically I have a fact table that holds details on events.   Each event can be categorized, but at different levels.  I have a category dimension that holds all the categories, subcategories.   There are three levels of categories.  Some categories have subcategories while others do not.  </p>
  
  <p>When I'm browsing the dimension I get drill downs for each item but the drill-downs sometimes end up displaying blank items(blue circle, no text).</p>
  
  <p>So I guess I have a category dimension that is holding categories of different granularity.</p>
  
  <p>I have been playing around with the settings for NULL processing and UnknownMember without really understanding fully how it affects things.</p>
  
  <p>Perhaps someone out there can give me a few tips or advice on the issue.</p>
  
  <p>I'm using SQL Server 2012</p>
  
  <p>Thanks</p>
