“The cube cannot be browsed verify that the cube has been deployed and processed”. This is probably the most misleading error message in Analysis service.
It is saying there is no cube out there but what is actually happening is you don’t have enough permission to read the cube. I have two role groups in the analysis service and the readers could not see my cube
Even though I gave the members permission to read the definition they can’t access the cube
So to fix this click on Cubes tab on the left and then change the Access from None to Read.
That should fix the problem for you.
