Which statement is false regarding references between rulesets configured as Application Validation?

In the context of application validation in Pega, the concept of ruleset referencing is governed by the hierarchy and configuration of rulesets. Particularly, rules from a lower-level ruleset can reference rules from a higher-level ruleset, but the reverse is not permitted.

When considering why the statement about rules in ClaimsFW being able to reference rules in Claims is false, it's critical to understand that ClaimsFW is a higher-level ruleset than Claims. This means that while rules in the Claims ruleset can reference rules in ClaimsFW, the reverse is not valid. Rules in a higher-level ruleset cannot be directly referenced by rules in a lower-level ruleset in the specific context of application validation.

Thus, the other statements hold true based on the established referencing rules in Pega applications. For instance, the first statement is valid since the ClaimsInt ruleset, as a lower-level ruleset, can reference the higher Claims ruleset. Similarly, the fourth statement is true as ClaimsFWInt can build upon and reference the higher-level ClaimsFW.

The validation ruleset hierarchy indicates that a clear referencing rule exists where the direction of referencing is strictly enforced, clarifying why the assertion related to ClaimsFW referencing Claims is false.
