Development

Quick answer

Follow the clean-core principle: build extensions on approved frameworks (side-by-side on BTP, or in-app via released APIs), not by modifying standard, so your apps survive upgrades and cloud moves.

Key takeaways

SAP Business Application Studio (BAS) is the cloud development environment for Fiori/UI5, with wizards, templates (including Fiori…
Often you extend a standard Fiori app (adding a field or logic) rather than building from scratch, using approved extension points.
CDS views: model the data on HANA.
Watch out: Freestyle builds where Fiori Elements + RAP fit.

The modern development stack

CDS views: model the data on HANA.
RAP (ABAP RESTful Application Programming): define behaviour and expose OData services.
OData: the service the app consumes.
UI5 / Fiori Elements: the front-end, template-driven where possible.

Where you build

SAP Business Application Studio (BAS) is the cloud development environment for Fiori/UI5, with wizards, templates (including Fiori Elements) and deployment tooling. ABAP Development Tools (ADT) in Eclipse handle the CDS/RAP backend. Together they are the modern Fiori toolchain.

Extending standard apps

Often you extend a standard Fiori app (adding a field or logic) rather than building from scratch, using approved extension points. This keeps you close to standard (clean core) while meeting the specific need.

Clean core

Follow the clean-core principle: build extensions on approved frameworks (side-by-side on BTP, or in-app via released APIs), not by modifying standard, so your apps survive upgrades and cloud moves.

Common pitfalls

Freestyle builds where Fiori Elements + RAP fit.
Modifying standard apps instead of using extension points.
Ignoring clean core, painful upgrades later.

Frequently asked questions

What does the term Development refer to in SAP?

Fiori development builds custom apps and extensions when standard apps do not meet a need. Modern Fiori development uses the RAP model, CDS and OData on the backend with UI5/Fiori Elements on the front-end, developed in Business Application Studio.

Where does Development sit in the Fiori stack?

CDS views: model the data on HANA. RAP (ABAP RESTful Application Programming): define behaviour and expose OData services. OData: the service the app consumes.

What is the practical takeaway on Development?

Follow the clean-core principle: build extensions on approved frameworks (side-by-side on BTP, or in-app via released APIs), not by modifying standard, so your apps survive upgrades and cloud moves.

What tends to go wrong with Development?

Freestyle builds where Fiori Elements + RAP fit. Modifying standard apps instead of using extension points. Ignoring clean core, painful upgrades later.
