What is created to run automatically when a specific property value changes?

The appropriate choice is to use declare on-change rules because they are specifically designed to trigger an action automatically whenever a specified property value changes in the Pega application. This allows for real-time responses to data changes, such as recalculating values, updating user interfaces, or executing logic.

By utilizing declare on-change rules, developers can ensure that the system behaves dynamically based on users’ inputs or changes in data, enhancing the application’s responsiveness and functionality. This automation helps maintain data consistency and allows various mechanisms within Pega to act immediately when relevant changes occur, streamlining processes without requiring manual intervention.

On the other hand, activity rules are used for executing tasks or processes within Pega but are not specifically tied to property value changes. Data pages serve the purpose of managing and accessing data effectively, while service level agreements (SLAs) help manage the timing and delivery of work within the case management aspect but do not pertain to the automatic triggering based on property changes.
