OLAP data must be updated after data warehouse data is changed. You process OLAP cubes, dimensions, and partitions to incorporate new or changed data from the data warehouse. The method of processing an OLAP object depends on the object and type of change made to the data warehouse, such as data addition, data change, or structural change. You can use the incremental update, refresh data, or process methods to update cube data. Dimensions can be updated with the incremental update or rebuild the dimension structure methods. Partitions can only be updated with the process method.
