Introduction to Application Programming on SAP S/4HANA

This course provides participants with an overview of the ABAP RESTful Application Programming Model (RAP). The goal is to create an SAP Fiori app touching every area needed to develop and deliver this app to the SAP Fiori launchpad.

After a short introduction to SAP S/4HANA and SAP Fiori, the first step is to create CDS projection views on top of existing data model views using the ABAP Development Tools (ADT). Exposing the CDS projection views as a business service makes it possible to consume the model data in a SAPUI5 app, which is built using SAP Fiori elements.

Using the behavior of a RAP business object, transactional processing is enabled in the app. Determinations, validations and actions are also added through this. As additional functionality draft-support and value helps are implemented. To make the app available in the SAP Fiori launchpad, catalogs with tiles and target mappings are created.
