# RAP640 - Using ABAP Cloud to Build Extensions for SAP S/4HANA Cloud, Private Edition - Mitigating Missing Released SAP APIs in the 3-tier Extensibility Model

## Description

This repository contains the material for the hands-on session **RAP640 - Mitigating Missing Released SAP APIs in the 3-tier Extensibility Model** which is about mitigating missing released SAP APIs in the 3-tier Extensibility Model when building apps, services, and extensions with the ABAP Cloud development model on SAP S/4HANA Cloud Private Edition and SAP S/4HANA.

## 📋Requirements for attending this workshop 

[^Top of page](#)

To complete the practical exercises in this workshop, you need the latest version of the ABAP Development Tools for Eclipse (ADT) on your laptop or PC and the access to a suitable ABAP system - i.e. at least release 2022 of SAP S/4HANA Cloud Private Edition and SAP S/4HANA.

  Click to expand!

The requirements to follow the exercises in this repository are:

1. [Install the latest Eclipse platform and the latest ABAP Development Tools (ADT) plugin](https://developers.sap.com/tutorials/abap-install-adt.html)

2. [Adapt the Web Browser settings in your ADT installation](https://github.com/SAP-samples/abap-platform-rap-workshops/blob/main/requirements_rap_workshops.md#4-adapt-the-web-browser-settings-in-your-adt-installation)   

> ℹ️ **Regarding SAP-led events such as "ABAP Developer Day" and "SAP CodeJam"**:   

> → A dedicated ABAP system for the hands-on workshop participants will be provided.   

> → Access to the system details for the workshop will be provided by the instructors during the session.

## System access (workshops provided by SAP)

In a workshop that is conducted by SAP a SAP S/4HANA 2023 preconfigured appliance system will be provided to the workshop participants. 

The system details will be provided by the trainers. With the system details you can connect via ADT to the system as described in the following how-to-guide.

## 🔎Overview

[^Top of page](#)

Learn about the current business scenario and the 3-tier extensibility model.

### About the Business Scenario 

  

In this hands-on workshop, we will guide you through the development of a custom wrapper for the ABAP Cloud enablement of an unreleased SAP BAPI for creating purchase requisitions, then a custom RAP BO and UI service on top of it to develop a transactional, design-capable, Fiori Elements-based list report app using RAP. Finally, you'll use your custom API wrapper in your custom RAP BO to integrate your custom app with the standard professional SAP Purchase Requisition app.

The resulting app will look like this:



  

To set the business context, the scenario is the following: This demo scenario shows a custom and SAP Fiori elements-based shopping cart app built on-stack with RAP. The custom app is integrated with the standard Purchase Requisition app in SAP S/4HANA Materials Management using a custom wrapper on top of the unreleased SAP API `BAPI_CREATE_PR`.

### About the 3-Tier Extensibility Model

You will learn how to apply the [Cloud API Enablement Guidelines for SAP S/4HANA Cloud Private Edition and and SAP S/4HANA](https://www.sap.com/documents/2023/05/b0bd8ae6-747e-0010-bca6-c68f7e60039b.html) to consume an unreleased SAP API. You will learn how to mitigate missing released SAP APIs in the 3-tier extensibility model when working with ABAP Cloud on these two products.

## 🛠Exercises

[^Top of page](#)

Follow these steps to build a custom wrapper for the ABAP Cloud enablement of an non-released SAP API for creating purchase requisitions, then a custom RAP BO and a UI service on top of it for a transactional, draft-enabled Fiori Elements list report app. Finally, you'll use your custom API wrapper in your custom RAP BO to integrate your custom app with the standard professional SAP Purchase Requisition app.
