In ServiceNow, the concept of domain separation allows for data and administrative segregation between different domains within an instance. When a business rule is defined in a parent domain, it applies to that domain and all child domains unless specifically overridden in a child domain1.

If a business rule is overridden in a child domain, the original rule in the parent domain continues to apply only to the parent domain and any other child domains that have not overridden the rule. The overridden rule in the child domain applies only to that specific child domain1.

Therefore, for the parent domain, the business rule that was created in the parent domain will run. The child domain’s override does not affect the operation of the parent domain’s business rules. This ensures that each domain can have customized behavior while still inheriting the broader rules set at the parent level.

It’s important to manage these rules carefully to maintain the intended data integrity and operational workflows across different domains within the ServiceNow environment4.

The system property glide.sys.domain.delegated_administration is designed to empower customer administrators by allowing them to configure their own domains. This is crucial in a multi-tenant environment where multiple customers or departments are operating within the same ServiceNow instance but need to maintain separate configurations and data. By enabling this property, customer admins can make changes specific to their domain without the risk of affecting the configurations of other domains. This property essentially enables domain separation, which is a method of separating data into logically defined domains.

Best practices for setting up a domain hierarchy in ServiceNow recommend creating a structure that is not too shallow or too deep. A hierarchy that is 3-5 layers deep is considered optimal as it allows for the use of ‘contains’ relationships where necessary12. This structure should include a default domain, which typically serves as the catch-all layer for any data that does not belong to a more specific domain3. The default domain is often the TOP domain or a domain just below it. This setup facilitates better organization and management of data and processes across different domains within the instance45.
