Business A business rule is a server-side script running at the moment of inserting, updating, or deleting a record.  Business 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.

The scheme below illustrates when before, after,andasync after rules run. All rules execute after an action record start (insert, update, or delete).

Process 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 – 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).

Out-of-the-box business rules override 

Anchor
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:

(function executeRule(current, previous = null /*not null only when action is update*/) {
  if (previous) {
    current.subject = previous.subject;
  }
})(current, previous);
