A business rule is a server-side script running at
whenthe moment
whenof inserting, updating, or deleting a record.
them forBusiness rules are used for such tasks as conditionally automatic value change in the form fields or event creation for email
notifiesnotifications and script actions.
Info |
---|
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 asclient -sidescripts and UI-actions. |
The scheme below illustrates when Before and After rules run.

Before Rules run conditions:
before, after,andasync after rules run. All rules execute after an action record start (insert, update, or delete).
The process starts with a form action: if it is the update action, the data source is the database, and therefore the record has the previous block. The previous block represents a form condition before an 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.
Image Added
Before rules run conditions:
- After record action start (insert, update, or delete).After a user submits the form;
- Before the system performs the server updates.
After rules run conditions:
After a user submits a form;- After the system performs the server updates.

Abort Business-rules
It is possible to perform business-rules that terminate the follow-up actions and processesAsync after rules run conditions:
- After all business rules of other types (after all after business rules).
Info |
---|
The abort Async after business -rules terminate the following processes: Business-rules, Notifications, Approval Rules, and etc. |
To make your business-rule abort the follow-up processes, complete the steps below:
- Open the business-rule desired.
- On the form, check the Abort Action box.
- Click Save or Save and Exit.
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. |

The server-side business logic may not work for system tables if the creation or updating of records is initiated by the backend. For example, an Import Set is created as part of loading an Import Source, or an Email is created as a result of a notification rule, and so on.

Out-of-the-box business rules override Anchor override override

override |
If necessary, some out-of-the-box business rules can be overridden.
- For applications other than Simple, it is sufficient to copy an out-of-the-box rule using the Make a copy action and deactivate the original rule. Then you can determine the required logic in the copy of the rule.
- For the Simple application, the majority of the rules are delivered withProtection Policy = Protected, thus you can not simply deactivate them. However, the rules of the When=before type can be overridden by rules with the same start conditions of a higher order. For example, an out-of-the-box rule with the before type generates a value in the Subject field. The order of the rule is 999. To change the value generation logic, it is sufficient to make a copy of the rule using the Make a copy action, determine a specific logic and set Order = 1000. If the value in the field must remain unchanged, use the rule triggered by an Action Update event with the following script:
Code Block | ||||||||
---|---|---|---|---|---|---|---|---|
| ||||||||
(function executeRule(current, previous = null /*not null only when action is update*/) {
if (previous) {
current.subject = previous.subject;
}
})(current, previous); |
