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

[Lindy hagan]

nope, I am not looking for that.

This is my requirement: If I have 10 rules say from rule 1 to rule 10. If
rule 3 is satisfied, should not check for rule 4 to rule 10.

We cannot achieve the above scenario using "activation-groups".
