Hi,

Using Kogito as a rule engine, is there a way that for a cart discounting system we could deactivate a rule after it has been fired a fixed number of times - considering of course the the rule could be fired over scores of different nodes in a cluster?

regards
John

Hi,

I suspect in this situation you would have to maintain a counter outside of the rules and check if the discounts have run out. Then pass in the amount either when the rules are fired or fetch the count with the rules during evaluation ( if possible ).

Now to keep track of how many times a rule has fired. I feel like it would be most simple and clear for the rule authors if the counter was updated in rule LHS.
