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.
