[rules-users] Using accumulate function

Hi, Iam trying to use the accumulate function of the drools.I need to accumulate based on the result of a rule execution. Eg: Suppose i have list of orders and another list of conditions for a particular package.I need to check weather each of the order is part of package or not. Suppose a qty limit is set to 1 for a item in package definition and the item is ordered 2 times. While checking the condition, both of the item will go under package. Actually for second record the rule should get executed based on result of the 1 record's rule execution and so on. So I require a looping rule execution. How can i achive this using Drools. Rule "Package Rate_21" salience 65515 when $objOrderedComponents:AccumulatedComponent() $packageDefinition:PackageDefinition($packageId:packageId) $accumulatedQty:Number() from accumulate( $accQtyComponent:OrderedComponent(packageChargeRecordId==$packageId, $AccQty : componentQty) from $objOrderedComponents.getOrderedComponentList(),sum($AccQty ) ) $orderedComponent:OrderedComponent($id1:componentKey,$qty:componentQty) from $objOrderedComponents.getOrderedComponentList() and $pkgComps:PackageComponent(componentKey==$id1,(quantityLmt $packageDefinition.getPackageComponentList() then $orderedComponent.setIsComponentApplicable(true); $orderedComponent.setPackageChargeRecordId($packageId); end Regards Sanal.P -- View this message in context: http://drools.46999.n3.nabble.com/Using-accumulate-function-tp3896078p389...
