In ServiceNow, Business Rules are server-side scripts that execute whenever a record is inserted, updated, deleted, or queried. However, certain actions can be configured without writing any script, using the Business Rule's user interface options.
The primary actions that can be configured without scripting are:
* Set field values: This allows administrators to specify new values for fields when the Business Rule conditions are met. This is configured in the "Actions" tab of the Business Rule form, where specific fields and their desired values can be set without any scripting.
* Add message: Administrators can configure a message to be displayed to the user when the Business Rule executes. This is done by selecting the "Add message" checkbox and providing the desired message text.
Options C (Set field values and write to the system log) and D (Set field values and generate an event) would require scripting. Writing to the system log involves using server-side APIs like gs.log(), and generating an event requires calling event generation methods-both necessitate scripting.
