Thanks, Michael, for your good explanation. Another thing I want to
add for Jim is that each "BatchInboundTransactions" line on the
rule's left hand side matches a single BatchInboundTransactions
object independently; in other words, if you've got ten such objects,
then this rule matches all of them in 10 to the sixth power (one
million) different combinations, and the logic applies to values
extracted from any combination of those objects. I'm almost certain
this is not what you intend; I'm pretty sure you want all the values
to come from just one object. To do this, you'd have just one
"BatchInboundTransactions" line with all the slot qualifiers in it;
i.e.,
(defrule Jim_Rule "Jim Rule Comment"
(BatchInboundTransactions (inbound_id ?inId)
(facilitycode ?facilitycode)
(amount ?amount)
(rvu ?rvu)
(quantity ?quantity)
(costctr ?costctr)
(servicecode ?servicecode))
If you are guaranteed to only ever have a single
BatchInboundTransactions object, then what you've written will have
the same effect -- it will just be unnecessarily inefficient.
