Alternate Hierarchies An alternate hierarchy may be modeled in either of the following ways: ● As an attribute dimension, which uses attributes to classify members logically within the dimension (for example, a Product dimension can have attributes such as Size and Flavor.) As a hierarchy of shared members. The alternate hierarchy has shared members that refer to non shared members of previous hierarchies in the outline. The shared members roll up according to a different hierarchy from the non shared members to which they refer. Shared members on dynamic hierarchies can have formulas. The non shared instance of the member must occur in the outline before any shared instances of the member
