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, after, and async after rules run. All rules execute after an action record start (insert, update, or delete).
Process starts with a form action: if it is the update action, data source is the database, and therefore the record has the previous block. The previous block represents form condition before action (form submission – insert, update, or delete), and the current blocks represent a form condition after the action is completed. Form submission can be performed by a user, script, or REST API request.
Before rules run conditions:
- After record action start (insert, update, or delete).
- Before the system performs server updates.
After rules run conditions:
- After the system performs server updates.
Async after rules run conditions:
- After all business rules of other types (after all after business rules).
Async after business rules run after before and after business rules, so first, a user receives the form with all changes, and then async after rules run. Thus, using async after business rules, you can optimize system response time – use async after rules for resource-intensive scripts that take a lot of time.
Role required: admin.
