Attribute relationships define functional dependencies between attributes. If attribute A has a related attribute B in a hierarchical relationship, then an attribute relationship can be defined that assists Analysis Services to aggregate data.
Note
Attribute relationships require unique members in order to function correctly—if there are duplicate values participating in an attribute relationship then cube data can be incorrectly aggregated and displayed.
