[rules-users] Help with Accumulate function

[Wolfgang Laun]

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.
