Key concepts

First, know what extension means. It is adding features without changing core code. Second, know the two layers. Frontend is UI changes. Backend is service and data changes. Third, know upgrade safety. Extensions must be safe in upgrades.

Why extend instead of rebuild

First, it is faster. Next, it keeps support from SAP. Also, it reduces risk.

Finally, it reuses tested code. This is why many teams choose extension.

Key differences and methods

Extend Fiori Apps via UI adaptation and custom controllers.
Extend Fiori Apps in backend using BTP services. UI methods include UI5 component extension and annotations. Backend methods include CAP services and ABAP extensions. Each method fits different needs.

Step-by-step extension process

1.    Assess the need. Write simple goals.

2.    Choose layer to extend. UI or backend.

3.    Prepare a sandbox. Use a copy for work.

4.    For frontend, use UI5 extensibility points.

5.    For backend, add CAP or OData extensions.

6.    Test thoroughly in sandbox.

7.    Deploy to a test landscape.

8.    Validate during a real user scenario.

9.    Move to production when stable.
