Status Expression
An MDX expression that represents the state of the KPI at a specified point in time.
The status MDX expression should return a normalized value between -1 and 1. Values equal to or less than -1 will be interpreted as "bad" or "low." A value of zero (0) is interpreted as "acceptable" or "medium." Values equal to or greater than 1 will be interpreted as "good" or "high."
An unlimited number of intermediate values can optionally be returned and can be used to display any number of additional states, if supported by the client application.
