Master Data Governance — Custom Business Objects & Integration Flows
Building custom RAP business objects for master data governance in S/4HANA, and the integration flows connecting SAP BTP with SAP ERP through the SAP Integration Suite.
What I delivered
- Design and develop custom Business Objects in SAP S/4HANA using the RAP model and ABAP OOP for master data governance requirements.
- Build integration flows through the SAP Integration Suite, connecting SAP BTP and SAP ERP systems.
- Apply clean-core principles — extensions built on released APIs and ABAP Cloud rather than modifications to standard objects.
Context
My current work at Laidon Group, starting May 2026. The focus is master data governance: making the creation, review, approval and distribution of master data an explicit, auditable process rather than something that happens by convention.
The technical shape
RAP business objects. Each governed object is modelled as a RAP business object — CDS data model, behaviour definition, behaviour implementation, projection view, service definition and binding. The behaviour definition is where the governance rules live: which fields can change in which state, what validations must pass, and which determinations fire on save.
Integration Suite. The iFlows that move approved master data out to consuming systems, and bring change requests in.
BTP ↔ ERP connectivity. Destinations, communication arrangements and principal propagation — the plumbing that lets an extension running on BTP act on ERP data as the right user, with the right authorizations.
Why RAP rather than classic ABAP
For a governance process specifically, RAP earns its complexity. The framework gives you draft handling, optimistic locking, a state model, and a consistent transactional contract — all things you would otherwise hand-write badly. And because the object is exposed as an OData V4 service by construction, the Fiori UI and any system integration consume the same definition of what is valid.
In progress. This engagement is ongoing — I will publish specific stories here as milestones complete.

Happy to walk through the technical decisions in a conversation.
