Ruleset Prerequisites
Hi Team,
In the below 3 bullet points, could you please explain the third one with an example? What is the need for the system assembling all lowered number ruleset versions of a ruleset (Let us say Ruleset X) and rulesets included in the same major version, when we save a rule in a ruleset X.
I am not able to understand what is the need of this 3rd poing when we save a rule.
Rule validation is performed against the prerequisites. When we save a rule, the system assembles a complete required ruleset version list from:
- All ruleset versions on this list
- All ruleset versions listed as prerequisites for those ruleset versions
- All lower-numbered ruleset versions of this ruleset and the rulesets included in the same major version

Hello Mohan,
Good question.
Point 3 is alluding to the fact that rule resolution does not include rules that are in a lower major version. Noted a little further below in the article:
"Note that rules in versions below the major version are not visible to rule resolution. For example, if you list Alpha:02-01-01 that depends on Beta:02-01-01, Alpha:02-01-01 won’t see rules in Beta:01-XX-XX."
So if you have rules in Beta:01-XX-XX there is an expectation that the skimming refactoring tool was used to skim the needed/used rules from Beta:01-XX-XX to Beta:02-01-01 when that major version was created. Reducing the number of rules that are no longer used or replaced due to versioning. Faster and more efficient for rule resolution.
I hope this helps clarify,

Hi Pottt,
Just want to confirm if the 3rd bullet
Rule validation is performed against the prerequisites. When we save a rule, the system assembles a complete required ruleset version list from:
- All ruleset versions on this list
- All ruleset versions listed as prerequisites for those ruleset versions
- All lower-numbered ruleset versions of this ruleset and the rulesets included in the same major version
is supposed to say All lower-numbered ruleset versions of this ruleset included in the same major version instead of All lower-numbered ruleset versions of this ruleset "and" the rulesets included in the same major version.
Thanks.

Hello MohanK54,
Lets say you are saving a rule in Alpha:02-05-01 which has a reference to the section in Alpha:02-04-22 and this section has a reference to a property in Beta:02-04-20.
Assume pre-requisites of Alpha:02-05-01 is Beta:02-05-01.
So in design time validation, the system checks the validations on every ruleset version of Alpha:02-xx-yy,Beta:02-xx-xx and the pre-requisites of Beta and so on. This is a cyclic form of validation since your new rule can have reference to any rule within the scope of the ruleset.
Thanks,
Ashok
