According to the ServiceNow Hardware Asset Management documentation, a business rule is a server-side script that runs when a record is displayed, inserted, updated, or deleted, or when a table is queried. Business rules can be used to enforce data consistency and integrity, such as preventing duplicate transfers of the same asset.
