Trainingsbeschrijving

Naar boven

This course is a deep dive into the ABAP RESTful Application Programming Model. The primary focus lies on the transactional behavior of business objects and their consumption in OData UI services.

You will learn to define business objects which consist of just one data node, as well as business objects consisting of a hierarchy of nodes.

When implementing the transactional behavior, you will first use the generic data access layer (managed approach). Later you will also integrate existing legacy code (unmanaged or partially managed approach).

You will draft-enable your business object and produce and consume business events. Finally, you will enable the extensibility of your business object and learn how to extend existing business objects.

The course is held on SAP BTP, ABAP environment. However, most of the content is equally suitable for SAP S/4HANA cloud editions and SAP S/4HANA 2020 or later. Some features shown in the course may not be available in older SAP S/4HANA releases.
