  <p>Any Idea?
  i searched in google. I saw similar errors and feedbacks. But most of them dealing with SQL 2008/2005 edition issues etc..</p>
  
  <p>Here my SSAS designer and SQL server source are 2012. Asking in stack-over flow, after reading many confusing blogs..</p>
  
  <p>Thanks in Advance.</p>
