A rule set is a logical cluster of Business Rules that belong together for some special, often technical reason other than because they cover the same topic (Business Objects and Business Areas are used for this) or because they cover the same business process (Business Process Steps and their child Business Rules are used for this) .
Rule Sets belong to Business Areas but not to Business Objects. Consequently, Rule Sets can be used for classifications that cut across the functional topics represented by Business Objects.
Examples of Rule Sets are:
In USoft 6.2 and earlier, Rule Sets were the only way to relate Business Rules to process-related concepts. With the introduction of Business Process Steps in USoft 7, it is now suggested that such process-oriented Rule Sets are best converted to Business Process Steps.
