Thanks Wolfgang.
The issue here is that the accumulation has to happen at a higher level in
the object hierarchy, Position in this case. However, this is no direct
link between Position and PostitionPnlAttributionAmount ( which is being
accumulated). How do I tackle such a scenario?
$attibAmtType will be just one for the condition given, but there could be
multiple $posPnlAmt within a Position.
Thanks,
Dwipin

Well, this explains it - you'll have to find the selecting combination
of $posPnlAmt and $attibAmtType in a unique way, assuming there is
just one such combination.

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.

Repeated firing may be due to there being more than one scope for
accumulating
the sum, as selected by the patterns leading up to the accumulate.
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.

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.
Thanks for any help,
Dwipin.
