Navigational attribute is not seen in query designer columns. How I can show?

Hi I have navigational attribute in the master data object. Its mapped upto last DSO but not mapped in the cube.

It is not assigned in the multiprovider. When I am in the query designer I can see it in the rows. But I can not drag it to columns to make some calculations based on that. I want this in clumns without assigning it in multprovider because it will need multiprovider activation and all things. Multi provider contains very larger number of cubes. Please help me in this. Thanks in advance.
