Problem Note 40549: Optimization code might cause additional queries when accessing aggregation data
 |  |  |  |  |
When the SAS® OLAP Server receives a query, it makes an attempt to optimize the query using either the NON EMPTY operator and the CROSSJOIN function or the NONEMPTYCROSSJOIN function. This optimization process can cause extra subqueries to be sent to the data layer. In the case of ROLAP cubes, this means additional SQL queries are sent to the RDBMS in which the data is stored.
