Rule Set 
Grouping of rules that belong together from a business point of view, and that are distributed over several events.
You can use rule sets to map simple units for managing rules. For example, you can jointly activate or deactivate the rules of a rule set.
A rule set comprises several rules that belong together from a business point of view.
The rules of a rule set have the same attributes as the rules that are directly assigned to the events (see Rule).
You can define a gate expression for a rule set. If the rule set is active, you can use the gate expression to control whether the rule set should be applied. You can define a gate expression for the individual rules in a rule set.
