[rules-users] filtering object having max value

Hi folks, I want to filter object instance in WM when max value of an object field (rental ) is less than X (reloadValue) . X will vary over time. I tried to use below query but I couldn't get expected results. Could anyone please help me? Thanks. -------------------------------------------- rule "Insuf-Balance-Reload Alert" dialect "java" when $re : ReloadEvent($rechargeNum : rechargedNumber,$reloadVal : reloadValue ) from entry-point "RELOAD-EVENT" InsufBalFailFact(mobileNo == $rechargeNum,$reloadVal > rental, $pkgId : pkgId,$rental : rental) not InsufBalFailFact(mobileNo == $rechargeNum, rental > $rental) then System.out.println($rechargeNum+","+$pkgId +","+$rental); end -- View this message in context: http://drools.46999.n3.nabble.com/filtering-object-having-max-value-tp402...
