Drools Experts: I have a list of the following fact objects sent to my rules: CrewSegment Date startDate Date endDate double crewHours int personId along with an object to designate seats: SeatAssignment int seatId int personId Here is the rule I want to enforce in English: No crew member (uniquely identified by personId) can have more than 56 hours of total crewHours in any 7 day period. The rule I've written so far is: when $s : SeatAssignment ( ) $total : Number( doubleValue > 56 ) from accumulate( CrewSegment( personId == $s.personId, $crewHours : crewHours ), sum( $crewHours ) ) This rule nicely catches any instance where more than 56 hours are committed by a person, but does not limit the time period to 7 days. How do I limit the search to be sure that it is 56 hours WITHIN 7 days, and not just 56 hours total over ANY time period? Thanks in advance for any help you can provide!!!
