Business Rules Questions
Create and manage business rules for server-side automation. Understand when business rules execute, how to use conditions and scripts, and best practices for server-side logic.
About Business Rules
Business Rules are server-side scripts that execute when database records are displayed, inserted, updated, deleted, or queried. They are one of the most powerful automation tools in ServiceNow, allowing developers to enforce data policies, automate workflows, and implement complex business logic.
Why This Matters for Your Exam
Business Rules account for 15% of the CAD exam. Questions focus on understanding the different types of business rules (before, after, async, display), when each type executes, and how to use the current and previous objects effectively.
Key Concepts to Master
Understand the four types of business rules and their execution order. Know how to use conditions vs scripts for rule logic. Learn when to use before rules (data validation/modification) vs after rules (related record updates) vs async rules (heavy processing).
Exam Tips
Remember that 'before' business rules can modify the current record without an explicit update() call, while 'after' rules require update() for changes to related records. Know that 'display' business rules run when a form loads and can set scratchpad values for client scripts.
