The helpdesk can also define business rules exclusively for Service Requests as well. Just like business rules of Incident Requests, these rules enable them to organize the incoming requests (via web form and e-mail) and perform actions such as delivering them to groups, assigning status and other request parameters. These business rules can be applied to a request: when it is created and/or edited or deleted permanently. They can also choose to notify a select group of technicians through mail/sms whenever a particular business rule is executed by configuring Notifications section of business rules for Service Requests as per their requirements.
To access Business Rules configuration page for Service Requests, go to Admin >> Service Catalog >> Service Catalog - Business Rules.
Business Rules are categorized and executed in rule groups. With rule groups, you can configure to apply/restrict selected rules on an incoming request. For example, consider two rule groups A and B, where A contains rules based on priority and B contains rules based on level. For an incoming request, you can choose to apply the first two rules configured in group A and then skip to apply rules from group B.
