The challenge

What the solution needed to change.

The implementation required backend services that could expose structured business data to custom Fiori applications while fitting the wider S/4HANA technical landscape.

Delivery also needed coordination across functional, Fiori, BASIS and other technical teams so service contracts, backend logic, testing and issue resolution stayed aligned.

Technical approach

Architecture shaped around maintainable control points.

Layered OData services were delivered through SAP Gateway to separate the Fiori-facing service contract from underlying data retrieval and application logic.

Supporting ABAP on HANA developments included object-oriented and procedural reporting, CDS views, interfaces, enhancements, user exits and BAPI/function-module-based conversions where required by the implementation.

01Requirement

Functional and Fiori needs are translated into a clear backend service contract.

02Data model

Entities and relationships define the information exposed through Gateway.

03Backend logic

ABAP and CDS retrieve, transform and validate the required SAP data.

04Service delivery

OData operations expose the approved contract to the Fiori application.

05Cross-team validation

Testing and issue resolution are coordinated across delivery teams.
