The default value for this property depends on the value of the ClassType property of the object.

If you generate the aggregation by using an object of ClassType clsPartitionAnalyzer, the system automatically sets IsDefault to True. Generating aggregations in this way has performance benefits and is the recommended method for generating aggregations. If you generate the aggregation without using a partition analyzer object, you should set IsDefault to False. |

True if the partition is the only one in the cube, False otherwise. |
| Hinweis |

This property does not indicate that an aggregation object is the default within a collection of aggregations. If set to True, it indicates that the aggregation object contains the default dimensions and measures of the partition, which are already stored in the repository. This reduces the size of aggregation metadata, which can become important when a partition contains a large number of aggregations. |
