1. Configuration Entry

In Object Management → Layout, click "UI Events" in the global settings to configure. (UI events are configured in detail pages. However, if the create/edit page layout is enabled, configuration should be done there instead.)

• Child objects cannot trigger UI events
• UI event execution results only apply to create/edit pages and take effect upon saving
• This feature is only available in Enterprise and Group editions
