(Sorry if this gets posted twice I had the wrong e-mail registered)

We tried setting the maxConstraints = 100 however the same error
occurred. It looks like this issue is caused in part by the large volume
dimension at the parent level (200,000). 

There appears to be some code that results in the in clause not to be
created (from Mondrian 2.2.2 source for class SqlConstraintUtil):

            ColumnConstraint[] cc = getColumnConstraints(c);

            if (!strict && cc.length >=
                // Simply get them all, do not create where-clause.
                // Below are two alternative approaches (and code). They
                // both have problems.

            } else {
                String cond = RolapStar.Column.createInExpr(q, cc,
            if (level.isUnique()) {
                break; // no further qualification needed
In our case the number of ColumnConstraints (200,000) exceeds the max
constraint property (100), however the strict variable is always true.
Under what circumstances would this be false? We also tried Mondrian
2.3.2 but received the same error. 

Thanks for your help,
