Am trying to create a new measure but keep getting error:"Item with the same key has already been added"Meanwhile, no measures exist for my model as far as sql server management studio is concerned and none are in the model either.I do not understand what is meant by 'item' or 'with same key'.Can someone advise how to fix. I am getting this error as a consequence of trying to make headway on the other issue I have posted here!!!:w00t:
