Represents an instance of a defined Aggregation for a partition.
Assembly: Microsoft.AnalysisServices (in Microsoft.AnalysisServices.dll)
When a Partition uses an AggregationDesign to generate aggregations for that partition, each Aggregation in the AggregationDesign is instantiated for that partition. Multiple partitions can use the same AggregationDesign to generate multiple instances of a defined Aggregation. Also note that user defined aggregations can be created on a partition without going through the AggregationDesign object.
