KPIs and Calculated Members

A Key Performance Indicator (KPI) is a collection of calculations that are used to
measure business success. A calculated member is a member of a dimension or
measure group that is defined based on a combination of cube data, arithmetic
operators, numbers, and functions. KPIs are added using Cube Designer in BIDS
after a project has been generated. The calculations that comprise a KPI are a
combination of Multidimensional Expressions (MDX) and calculated members
that are also added using Cube Designer. A KPI is generally comprised of the
value achieved, a goal, a status value, and the trend.
