How to Classify Business Rules as Belonging to Other Rules
To make it easier to trace a business rule in a larger rule base, you can classify it as belonging to another Rule or to a Business Process Step.
To classify a business rule in this way:
If the rule you are classifying is a Business Process Step, then the Rule you are classifying it by must also be a Business Process Step.
Alternatively, if you are about to define a new Business Rule and you already know what other Rule or Process Step you want to classify it by, you can retrieve that Rule in the Business Rules and Processes window, click the Related Rules tab page, and then enter the new Rule on a new line on this tab page.
