This is not an Issue.

Based on the volumes of data of the client, it is impossible to do the CrossJoin they are proposing.

70 organizations * 35.048 bpartners * 31.975 products * 5.298.609 records in the fact table = 4,15 * 10^17

Mondrian itself is raising this problem:
'ResourceLimitExceededException: Mondrian Error: Size of CrossJoin result (21,974,101) exceeds limit (5,000,000)'

In this case the filters must be used to reduce the amount of data calculated and shown.

It would be nice if the application itself raises this problem to the user before attempting to launch the query.

The design defect that can be solved is to count the amount of records that each dimension is going to cross and, if it is higher than 100, raise an error forcing the user to select a filter.
