Master's in OData - Expert in Enterprise Web Service Modeling

Become the developer who exposes SAP to the world. Every SAP Fiori application, every mobile app and every external integration that consumes data from an SAP system goes through an OData service, and someone has to model it, implement it and maintain it well.

In this program you master SAP Gateway end to end: from system configuration to complete transactional services with batches and files, working on the service model that powers the vast majority of SAP ECC and S/4HANA on-premise systems today. The OData knowledge required by the official SAP developer certifications (Fiori Application Developer and Back-End Developer ABAP Cloud) is covered here in depth and on a real system.

  • 8 live 90-minute classes, one per week, on Fridays
  • Core technology: SAP Gateway and the OData protocol on ABAP
  • Direct hands-on work in an SAP system: SEGW transactions, Gateway Client and service maintenance
  • From zero to a complete transactional service: CRUD, navigation, batches and media objects
  • A direct foundation for RAP and OData V4: understanding Gateway means understanding what the modern framework generates for you

The journey, class by class

Each week you build on a real application. The journey ends with a final project and certification preparation.

    1st ed. Oct 2, 20262nd ed. Feb 19, 2027

    Entity modeling: from the dictionary to the service

    Three ways to model an entity and the judgment to choose the right one for each project.

    View content
    • Manual entity definition versus importing from dictionary (DDIC) structures
    • Generating models from RFC and BOR interfaces: reuse the logic that already exists in the system
    • Semantic annotations and search helps integrated into the model
    • Associations between entities and navigation properties: model header-item relationships the way SAP standard does

    Advanced modeling and the service lifecycle

    The elements that separate a demo service from a project service.

    View content
    • Function imports for operations that are not CRUD and complex types for nested structures
    • Referenced models and model reuse across services
    • Inside-out versus outside-in architecture: deciding where to model from and why

Final project

Program wrap-up: expert specialization in enterprise web service modeling

You close the journey with the two capabilities that make the difference in a professional-grade service: batch processing with $batch and media entities with file and image streams. You finish the program with the expert OData developer checklist and a clear view of where the model evolves with OData V4 and RAP.

OData has no dedicated certification exam: it is the cross-cutting knowledge required by the official SAP developer certifications (Fiori Application Developer and Back-End Developer ABAP Cloud), which you work on here in depth and on a real system, positioning yourself as a specialist in modeling the web services SAP uses to connect with the world.
