Which of the following are reasons to use the side-by-side extensibility pattern?

Using the side-by-side extensibility pattern is particularly beneficial when the extension utilizes its own data model. This approach allows developers to create extensions that operate independently of the core application, enabling flexibility and customization tailored to specific business needs. By leveraging its own data model, the extension can manage data in a way that aligns with its unique requirements, while still integrating seamlessly with the primary SAP S/4HANA system.

This model promotes agility and adaptability in development, as it shields the core ERP system from direct changes, minimizes the risk of conflicts, and simplifies upgrades and maintenance. It allows for a clean separation of concerns, where the core S/4HANA functionality remains stable, while the extension can evolve in response to changing business conditions.
