title: How to develop a reverse slicer in PowerBI?
body: <p>Please I need your help.</p>
  
  <p>I am doing a report in PowerBi in live connection.
  The model is in an azure analysis service and I am devolopping report with PowerBi. 
  I need to prevent the user from selecting the same value in both slicers</p>
  
  <p>In my report I have 2 slicers that are duplicated ( I am using them like a role playing dimension)
