What is the primary function of Dynamics 365's business rules feature?

The primary function of Dynamics 365's business rules feature is to enforce data validation and logic without the need for custom coding. This feature allows users to implement logic that can perform actions like setting field values, showing or hiding fields, or enabling and disabling fields based on certain conditions. By using business rules, organizations can ensure that data entered into the system meets specific criteria and adheres to business processes, all while using a no-code or low-code approach. This empowers users, often business analysts or system administrators, to make changes and maintain processes without requiring extensive programming knowledge or IT resources, thereby increasing agility and responsiveness in business operations.

The other options represent functions or features that do not relate directly to the primary purpose of business rules within Dynamics 365.
