A business rule is an action run on the server-side after submission of when a record form (when inserting, updating or deleting a record)is inserted, updated or deleted. Business rules are executed within in a database transaction, irrespective regardless of the interface used to initiate the transaction (a user submitting a form, the execution of a server-side script, a REST request, the execution of a Workflow Activity block). The rule action of a rule can be executed both on the current record and on other records.
Info |
---|
Business rules can use scenarios scripts to perform actions with records in the database. There are other options of the script actions available, such as client-side scripts and UI-actions. |
Business rules are used for:
- changing values in the fields of a record that caused the rule to run when certain conditions are met;.
- executing execution of a server-side script of the rule;.
- displaying a message to on the client side;.
- creating system events for sending e to send e-mail notifications or running other run other server-side scripts;.
- aborting interrupting database transactions with the database.
To view all business rules navigate to System DefinitionSettings → Business Rules.
To view the business rules related to a specific table, complete the following steps below:
- Navigate to the list or form view of the table;.
- Select Configure → Business Rules from the burger menu.
Business rules types
Depending on the business task to be completed, you can you are solving, use one of the following types of business rules:
- before;
- after;
- async after.
Each type of business rules has its own run conditions.
Before rules run conditions:
- After record action start (insert, update, or delete).
- Before the system performs server updates (before the database transaction is completed).
After rules run conditionscondition:
- After the system performs server updates (after the database transaction is completed).
Async after rules run conditionscondition:
- After all business rules of other types (after all after business rules).

Async The async after business rules run after before the before and after business rules, so the user first , a user receives the form with all the changes, and then the async after rules run. Thus, using async the async after business business rules, you can optimize system response time – use async the async after rules for resource-intensive scripts that take a lot of time. |
The following scheme below illustrates when the before, after, and async after rules run. All rules execute are executed after the start of an action record start on a record (insert, update, or delete).
Process The process starts with a form action: if it is the an update action, the data source is the database, and therefore so the record has the previous block. The previous block represents the form condition state before the action (form submission – submission – insert, update , or delete), and the current blocks represent a the form condition state after the action is completed. Form submission can be performed by a user, a script , or a REST API request.Image Removed

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 Impor 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. Example of tables for which server-side business logic may not work:

If necessary, some "out-of-the-box" business rules can be overridden.
- For applications other than Simple it is sufficient enough to copy an "out-of-the-box" rule using the Make a copy action and deactivate the original rule. Then you You can determine define the required logic in the copy of the rule.
- For the Simple application the majority of the , most rules are delivered with Protection Policypolicy = Protected, thus so you can not simply deactivate them. However, the rules of the When=before type can be overridden by rules of a higher order 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 a fieldthe Subject field. The order of the rule is 999. To change the value generation logic, it is sufficient enough to make a copy of the rule using the Make a copy action, determine define a specific logic and set Order = 1000. If the value in the field must should remain unchanged, use the rule triggered by an Action Updateupdate event with the following script:

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