- 5. 5 PUBLIC Motivation for Key User Extensibility in SAP S/4HANA UI Database UI Application App DB Side-by-side Extensibility on SAP BTP In-App Extensibility “De-coupled, Lifecycle-stable Extensions” De-coupling and Lifecycle Stability Challenge • Software is always patched and upgraded based on a fixed schedule and new innovations are introduced easily. Solution • Only extensibility that does not block SAP software updates and continue to work after an update without manual steps is allowed. • Custom extensions are lifecycle-stable, i.e. the software lifecycle of extensions is de-coupled from the systems of records (“clean core”). − Modification free − Clash free − Use whitelisted APIs and extension points − Compliant with zero-downtime principles

- 8. 8 PUBLIC SAP S/4HANA Key User Extensibility Scenarios SAP Fiori is a collection of apps with a simple and easy- to-use experience for broadly used SAP software functions that work seamlessly across devices – desktop, tablet, and smartphone. OData (Open Data Protocol) is an OASIS standard that defines the best practice for building and consuming RESTful APIs. CDS (Core Data Services) CDS is a modeling environment which provides a data definition language (DDL) for defining semantically rich database tables/views (CDS entities) in the database. The enhancements include annotations, associations, and (SQL) expressions.
