Re: [rules-users] Help with Accumulate function

Without the accumulate function, following is the fire occurrence- $position : Position() - 2 $posScn : PositionScenario(scenario == 'SCEN-EOD', position == $position ) - 2 ( with all above facts) $posScnGrp : PositionScenarioCurrencyGroup(positionScenario == $posScn, currencyType == CurrencyTypes.TRANSACTIONAL) - 2 ( with all above facts) $posPnlAmt : PositionPnlAmount(pnlAmountType == "DTD", positionScenarioCurrencyGroup == $posScnGrp) - 3 ( with all above facts) $attibAmtType : AttributionAmountType(attributionAmountType == "UNEXPLAINED/RESIDUALPNL") - 2 (just this fact) All of them together without the accumulate fires it 6 times.

If you take only the patterns preceding the accumulate - how often does this fire and for which elements? You need a single combination of $posPnlAm and $attibAmtType. -W On 7 April 2011 08:44, dwipin <dwipin.c(a)tcs.com&gt; wrote: Hi, I am having trouble implementing this rule with the accumulate function. My rule requirement is - Aggregate all PnlAttributionAmounts with a type of "UNEXPLAINED" for all Positions for a given day. Below is the code I have for this - $position : Position(date == $currDate) $posScn : PositionScenario(scenario == 'SCEN-EOD', position == $position ) $posScnGrp : PositionScenarioCurrencyGroup(positionScenario == $posScn, currencyType == CurrencyTypes.TRANSACTIONAL) $posPnlAmt : PositionPnlAmount(pnlAmountType == "DTD", positionScenarioCurrencyGroup == $posScnGrp) $attibAmtType : AttributionAmountType(attributionAmountType == "UNEXPLAINED/RESIDUALPNL") $totalPnlAttibAmt : BigDecimal() from accumulate( PositionPnlAttributionAmount(positionPnlAmount == $posPnlAmt, attributionAmountType == $attibAmtType, $pnlAttibAmt : financialValue) ,sum($pnlAttibAmt) ) eval ($totalPnlAttibAmt > 1000) When I do it this way, the rule gets executed 6 times, basically for every fact that evaluated to true. How do I restrict this? The rule should be executed only if the final eval results in true.
