After you select a primary item and/or the “default dimensions” item from the top pane, you can map domains and domain members from the dimension tree in the Dimension Members pane. When mapping domain and domain member, note the following:
Multiple domains and/or domain members can be mapped from different dimensions to the same fact value. For example, users can map the domain members “Soda” and “New York” to the same fact value.
Some taxonomies do not permit multiple mappings to the same fact value from the same dimension. For example, some taxonomies do not enable mapping the domains “East” and “West” from the “Regions” dimension to the same fact value.
Hypercubes and dimensions are always abstract and cannot be mapped to Office document data.
