Assigning a Hierarchy or Dimension
You must assign each calculated member, set
expression, and intersection (tuple) to a hierarchy or dimension.
We recommend that you select the hierarchy or dimension upon which
your calculation focuses. For example, if your calculated member is
based on years, select the Time hierarchy. If you create a calculated
measure, select the Measures dimension.
Select only a hierarchy that cannot affect the value of the calculation. For example, the hierarchy Camping Equipment has the same value no matter what Products context it appears in the report. Therefore,
- the calculation ([Camping Equipment]-[Mountaineering Equipment]) has a well-defined meaning only in the Products hierarchy, so select that hierarchy.
- the calculation tuple ([Revenue], [Camping Equipment]) can be assigned to either the Products or Measures hierarchy, as it is not affected by either context.
- the calculations ([2013] - [Camping Equipment]) and ([Fiscal Year 2013] - [Calendar Year 2013]) do not have a well-defined meaning in any hierarchy, and therefore cannot be used reliably at all.
