Which statement about Screen Aggregates is false?

The statement indicating that Screen Aggregates can only be executed when explicitly called is incorrect because, by default, Screen Aggregates run automatically without requiring an explicit call from the developer. This automatic execution occurs when the screen where the aggregates are defined is loaded.

Screen Aggregates are designed to efficiently manage data on a screen, automatically fetching the necessary data when the screen context is initialized. This eliminates the need for manual intervention to trigger their execution, streamlining the development process. The behavior of running automatically ensures that the data is readily available for the user interface as soon as the screen is presented.

The other statements present accurate information about Screen Aggregates. They run asynchronously and in parallel, which enhances performance and responsiveness. They also have a limited scope, functioning only within the screen where they were defined, thus maintaining a clean and organized flow of data.
