Dimensional Metrics
Dimensionality Allows the creator of a Metric to determine the level at which a Metric can be calculated.
All metrics, by default are given dimensionality at the “report level”. This means that the default level of calculation of a metric is according to the level of attributes on the template or report grid.
Any attribute can be specified as the dimensionality of a metric, thereby determining a level of calculation. If an attribute is specified, report level calculations will be overridden.
