In the SSA Mission - Circumstancing module - Multiple Variable Rule Circumstancing Topic:
-The last knowledge check section has the following question: If a rule is executed with the condition 'Dept=Engineering' which rules would be selected? The answer is a rule rule where the base version is in a higher RuleSet than the rule that is circumstanced for 'Dept=Engineering'...
but based on the Rule Resolution module, the circumstanced version is priority over RS version if the Applies to and Ruleset are the same....and this would allow for base rule updates to not force ALL circumstanced rules to update as well....
Am I missing something? or is knowledge check question incorrect?
Please review the Override a circumstanced rule slide in this same module which specifically discusses the Base rule flag which overrides prior circumstanced versions. It allows you to easily invalidate multiple circumstanced rules in prior rulesets.
During Rule Resolution algorithm while resolving the rule it will check the Applies to class and rule set and it will give initial preference to the circumstanced rules for that particular rule in the following order.
exactly matches a Circumstanced Rule
has the correct Circumstanced Date
is in the correct Date/Time Range
is the default Rule, with no qualifiers
I have verified the example in the module mission. In the options the rule is saved in to 01-01-25 and it is marked as base version and the same rule is saved in to 01-01-35 version. When the rule is marked as Base Version in the highest version than then all the circumstanced versions of that rule below that rule set version will obsolete. Now two are eligible 01-01-25 and 01-01-35. If 01-01-35 rule is not there then 01-01-25 will be picked as 01-01-35 is there and as it is the highest version of the rule above the base version it is picked.
Consider if the rule is not marked as base version in 01-01-25 and non circumstanced rule is saved in 01-01-35 then 01-01-20 will be picked as it is circumstanced version that satisfies the criteria.
