Defect - Drill on MDX expression based members

Another one for the defect list and this in my opinion impacts a feature that is most important and that was working in earlier releases.

The defect relates to drill up functionality on MDX based lowest level members.

To re-create the issue:

Create an MDX based query calculation, say children of Cooking Gear.

Drill up on TrailChef Water Bag                                        

Drill up on Cooking Gear         
                                    

Drill down on Golf Equipment        
                                  

Drill down on Putters       
                                          

Drill down on Course Pro Putter   
                                    

Drill up on Course Pro Putter 109110           

                       











We see children of Cooking Gear (the list we started with) instead of Course Pro Putter.

Seems like the drill functionality in 10.1.1 has a lot of defects not just in Business Insight but in Cognos Viewer as well.
