Adding a new field to a BI cube

Hi all, 

I am trying to add a new field to the Shared dimensions perspective, to an existing view. To be more specific, i am trying to add additional fields to CustTableCube view, fields SegmentId and SalesDistrictId. I add the fields, save the changes and go to update through Analysis Services project wizard.

However, the changes don't get picked up?

How to add a new field to the Shared dimensions perspective? 

Thanks,

Maja
