Hello,
Below there is an excerpt of what I am passing to the Rete engine, there
is a deftemplate for an order_item and two facts asserted as order items. I
need to write a rule which will detect if there is more than one line item
with the same patient id asserted. I have looked at the unique and exists
functions and they don't do exactly what I want. If I find two of the same
patients on the same order I want the rule to fire. There could be any
number of line items on the order. Thanks in advance for any help.
Sincerely,
Ryan Withers
