Rule resolution is the internal process by which Process Commander / Rules Engine decides at run-time which rule (of a set of candidate rules) to execute.

Below is the step by step process on how Rule resolution works to find the rule to execute :

1. Choose rule instance with correct purpose or family (rule type, rule name )
2. Discard rules with rules availability set to “Not Available” or “No” or “Draft”
3. Remove rules not in user’s ruleset list (ruleset & version)
4. Remove rules not in class ancestry
5. Sort rules (circumstance property , circumstance date , Date-time , version) group by class & ruleset
6. Discard rules(in Ruleset name & Major version) with rules availability set to “Withdrawn”
7. Discard multiple Default rules (across all “apply’s to” class & rulesets )
8. Display Error on rules with rules availability set to “Blocked”
9. Display Error where current users has restricted access
10. Finally, Select a Rule to execute

Below table explains, how Rule availability influences rule resolution :
