Hi, */"A planning entity should not use other planning entities to determinate its value range. That would only try to make it solve the planning problem itself and interfere with the optimization algorithms."/* reference to the above from the drools-planner user guide, I can use the other planning entity property but not to use other planning entity to determine its value range. Am I correct? thanks, ----- with kind regards, -- View this message in context: http://drools.46999.n3.nabble.com/planning-entity-value-range-type-tp4018...
