Introduction

TheABAP RESTful Application Programming Model (short: RAP) offers developers an efficient way to build enterprise-ready, SAP HANA-optimized, OData-based Fiori UI services and Web APIs in the cloud as well as on-premise. It is the evolutionary successor to the ABAP Programming Model for SAP Fiori.

TheABAP RESTful Programming Model is generally available in the SAP BTP ABAP environment, and now also in SAP S/4HANA starting with the edition 1909. Thefeature scope in SAP Business Technology Platform (BTP) ABAP Environment – formerly known as SAP Cloud Platform ABAP environment – is enhanced on a quarterly basis on defined dates, while new capabilities are delivered in SAP S/4HANA on a yearly basis with new on-premise editions. 

Thegreenfield development of OData – base service – i.e. , start from scratch – is support with the so – callmanage implementation type , whereas the brownfield development – i.e. , base on exist code – is support with the so – callunmanage implementation type .  

Thekey players in the ABAP RESTful Application Programming Model are:

ABAP Developments Tools in Eclipse	language : ABAP and CDS	powerful frameworks

TheABAP RESTful Application Programming Model comes with a set of development guides and best practices to facilitate the developer onboarding. Thebest practices are provided in the form of ready-to-use examples delivered with the ABAP Flight Reference Scenario ( refer to the appropriate section below ) .

ABAP Flight Reference Scenario

TheABAP Flight Reference Scenario is a new data model intend for demo purpose and use in training course – mainly in the context of the ABAP RESTful Application Programming Model ( RAP ) . It is is is a reloaded and adapt version of the well – know SAP NetWeaver Flight datum model .  

TheABAP Flight Reference Scenario offers several examples that can serve as reference implementations of the various capabilities provided by the RAP. It is not an integral part of the ABAP platform, but SAP – i.e. the ABAP Platform team –  makes it available and provides updates on GitHub. Therefore, it must be imported into the relevant ABAP systems before use. 

TheABAP Flight Reference Scenario is available by default and ready for use on the free SAP BTP ABAP environment trial.
