[rules-users] I want only first rule to be executed even more than one rule are fulfilling the LHS

[Edson Tirelli]

   Take a look at the manual on "activation-group"s. They allow you to do
that.

   Also, you can call fireAllRules(1) to fire only one rule, in case your
whole rulebase is like that.
