What is the purpose of the On After Fetch Event in aggregates?

The purpose of the On After Fetch Event in aggregates is to trigger actions after data has been successfully fetched from the database. This event allows developers to implement logic that needs to run once the data retrieval is complete, such as updating UI elements based on the fetched data, executing additional data processing, or setting up conditions for user interaction. By using this event, you can ensure that any actions dependent on the availability of the fetched data are executed only after that data is accessible, increasing the reliability and performance of your application.

Initialization of variables, resetting screens, and error handling primarily occur through different mechanisms in OutSystems and do not directly relate to the specific purpose of the On After Fetch Event. Each of these processes is important in its own right but serves distinct roles that are separate from the functionality of managing actions post data retrieval.
