SAP BTP, ABAP environment requires specialized knowledge of language limits and development environment—let this book be your guide! Begin by provisioning a trial instance and setting up ABAP Development Tools in Eclipse. Then, walk step-by-step through building an app using the ABAP RESTful application programming model, developing backend services, and creating SAP Fiori apps. Connect your cloud-based ABAP applications to on-premise and cloud systems and learn how to manage and maintain those applications. ABAP's not dead, it's in the cloud! Highlights include: 1) ABAP Development Tools in Eclipse
2) SAP BTP, Cloud Foundry environment
3) ABAP RESTful application programming model
4) Application development
5) Backend services
6) SAP Fiori
7) Consuming APIs
8) Identity and access management
9) Application lifecycle management
10) Monitoring and security

1 Getting Started

In this chapter, we’ll cover the prerequisite knowledge you’ll need for a good understanding of the SAP Business Technology Platform (SAP BTP) in general and SAP BTP, ABAP environment specifically. You’ll also learn how to set up the development environment, including how to create the development user required in the SAP BTP, ABAP environment itself.

First, let’s quickly go through the history of the SAP Business Technology Platform (SAP BTP), previously called SAP Cloud Platform. At SAP TechEd Las Vegas 2012, SAP announced plans for what was called at that time “SAP HANA Cloud,” a cloud platform based on SAP’s in-memory technology. Soon thereafter, at SAPPHIRE NOW 2013, SAP announced SAP HANA Cloud Platform, the platform that will serve as a foundation for all of SAP’s cloud-based solutions. Later, in 2017, this foundation was renamed SAP Cloud Platform, and then more recently to SAP Business Technology Platform, SAP’s platform as a service (PaaS) as we know it today.

In the beginning, SAP BTP was only available for the Neo environment—SAP’s proprietary environment, running exclusively in SAP data centers. Neo is a development environment for Java, HTML5, and SAP HANA extended application services (SAP HANA XS). Neo also offers the ability to use virtual machines (VMs), enabling scenarios that go beyond the native capabilities of the platform itself.

Cloud Foundry on SAP BTP was introduced at SAPPHIRE NOW 2017. Unlike Neo, the Cloud Foundry environment is open source and offers support for a wide variety of programming languages. Initially supported by SAP were Java and Node.js, and in 2018, ABAP was added. Besides these languages, Cloud Foundry supports other languages as well, following the bring your own language (BYOL) approach.

In this chapter, you’ll learn about the positioning of SAP BTP, Cloud Foundry environment and SAP BTP, ABAP environment. Before diving into SAP BTP, ABAP environment, we’ll take a step back and cover the basics in Section 1.1. You’ll also learn about ABAP Development Tools (ADT) for Eclipse development environments in Section 1.3. We’ll go step-by-step through the initial setup both on SAP BTP and on a desktop to prepare you for hands-on development. At the end of this chapter, in Section 1.4, we’ll cover initial set up of identity and access management (IAM).

1.1 SAP BTP, Cloud Foundry Environment

Cloud Foundry is an open-source platform, managed by the Cloud Foundry Foundation (https://www.cloudfoundry.org/foundation/). The Cloud Foundry environment can be hosted on any infrastructure, on-premise or in the cloud. All the major cloud providers—IBM, Amazon Web Services (AWS), Google Clou...
