Pega PRPC Revalidating all rules in a RuleSet

Summary
​Using a list view report on rules, a 5-step activity, and an HTML rule, you can revalidate all rules in one RuleSet, one RuleSet version, or a specific list of RuleSet versions.
The activity provides a comprehensive check of all rule types, in contrast to the Revalidate and Save tool which operates only on one rule type at a time.
If any rules fail validation, investigate and repair as needed. While validation does not ensure that a rule produces "correct" or "intended" results, execution of invalid rules is undesirable and often fails or produces incorrect results without warnings.

Suggested Approach

Each time a developer attempts to save a rule form, Process Commander performs numerous validation checks. Only rules that pass all these checks are saved.

So by definition, every saved rule was valid at one time, in a certain Process Commander system, when it was saved in a specific environment of other rules. However, at later times, or in other environments or other systems systems, a rule that was previously valid may become invalid. For example, rule ALPHA can become invalid if ALPHA depends on rule BETA but rule BETA was deleted after ALPHA was saved.

You can use the the built-in revalidator tool (accessed from the Developer portal menu Tools > Revalidate and Save ) to revalidate each rule of a single rule type in your RuleSets. For example, with this tool you can easily revalidate all the properties, or all the decision table rules, in one RuleSet. Revalidation adds a memo to the history of each rule that passes, even if the rule belongs to a locked Version.

However, it is sometimes helpful to revalidate all rules that meet specific criteria, such as all rules in a RuleSet, all rules updated since a specific date, or all rules updated by a specific developer.
​
The Data-Rule-Summary class supports reports on rules. (This class is linked to a database view, not a database table, in the PegaRULES database. See Related topics). If you can specify a set of rules to revalidate using exposed properties in this class, you can use the approach in this article.
