Sure. It's a simple (partial) solution for having a rule match in the absence of any other rules matching. It only works for columns with literal values and either the "equals" or "not equals" operator. In essence it builds a "in" or "not in" DRL statement. Section 4.10.1.4 Operation of "otherwise" in the Guvnor user-guide<http://docs.jboss.org/drools/release/5.3.0.Final/drools-guv... an example.

Thank u so much Mike and Welsh, Armand.

If you test for equality (==) then otherwise generates a rule with not in (?) If you test for inequality (!=) then otherwise generates a rule with in (?) The collection of the in and not in tests is the aggregate of the defined values in that column. See the URL for details.
