title: SSAS : Unoknow Members still shows on Report Slicer
body: <p>I have created Dimension - Vendors,Distributors and Time
  And I have Fact tables Purchase and Total Paid Amount.
  I have also set below properties for Dimension :</p>
  
  <p>UnknownMember : Hidden
  and for the Key Column Property
  NullProcess : Error</p>
  
  <p>I have also done properly Attribute Relationship on the Cube. So that it is giving me proper result as below.</p>
  
  <p><img src="https://i.stack.imgur.com/w8xFJ.png" alt="enter image description here"></p>
  
  <p>It is showing values without Unknown Members.</p>
  
  <p>Now, On my report I have put the slicer for the Venders.</p>
  
  <p>And it still shows Unknown as a member. I don't even have any null key in any table.</p>
  
  <p><img src="https://i.stack.imgur.com/Ij9fg.png" alt="enter image description here"></p>
  
  <p>Anyone has any idea, how to get rid of this unknown member with Best Practices?
  I am using SQL Server 2012 with Latest NU update. So that I can create Power View reports using connection on sharepoint site.</p>
  
  <p>Thank you,</p>
