A set based metric is a metric that contains a filter defined on a set, or the behavior within a set, for example, Joiners of the Gold Set. This type of metric is set to automatically refresh with the set at set processing time, rather than an independent refresh. Set based metrics are built using metadata in tables generated by Set Analyzer.
This
chapter introduces set based metrics and covers general design principles,
but does not provide specific workflows and examples based on the use
of Set Analyzer with Designer. Refer to the Performance Management Universe
Documentation for information on using sets for metric creation.
