Mondrian: Cannot seem to get Aggregation Tables to be used

Solution 1:

Might be the case mondrian­.­rolap­.­aggregates­.­Read is set to true and mondrian.rolap.aggregates.Use is set to false. Please set mondrian.rolap.aggregates.Use=true and check. Reference: http://mondrian.pentaho.com/documentation/configuration.php

If this is not the case, please attach all the properties related to aggregate tables and the complete cube definition XML.
