Business rule is a server-side script running at the moment of inserting, updating, or deleting a record. Business rules are used for such tasks as conditionally automatic value change in the form fields or event creation for email notifications and script actions.
Business rules can use scenarios to perform actions with records in the database. Even so, there are several other options of the script actions available, such as client-side scripts and UI-actions.
The scheme below illustrates when Before and After rules run.
Before rules run conditions:
- After record action start (create, update, or delete).
- Before the system performs the server updates.
After rules run conditions:
- After record action start (create, update, or delete).
- After the system performs the server updates.
For more information about execution order for before and after business rules, please refer to the Execution order article.
Role required: admin.
