Hi @BiswaRanjanRout ,
Based on my understanding, for high-performance processing in ServiceNow, Script Includes are generally preferred for implementing reusable and complex logic, as they execute only when explicitly called and can be reused across multiple components.
Business Rules, on the other hand, are best used as trigger points for specific database events (insert, update, delete) and should remain lightweight, typically delegating heavy processing to Script Includes.
This approach helps improve performance, maintainability, and scalability.
Hope this helps.
