This repository contains the material for the RAP hands-on workshop called RAP630 - Use ABAP Cloud for developer extensibility.

Developer extensibility as defined by SAP basically encompasses two activities

1. Develop custom code to implement your own business logic.

   Here you can make use of existing API's from SAP that have been released for that purpose.

2. Extend an existing RAP Business Object so that additional business functionality is added.

   Such an extensible RAP business object will usually reside in another software components or it is an existing extensible RAP BO that has been delivered by SAP or a SAP partner.
   By extending the funcitionality of an existing RAP Business object its functionality can be adapted to your specific business requirements.

This session introduces attendees to the ABAP Cloud programming model and how this can be leveraged how

• to build extensions (own code) in SAP S/4HANA BTP, ABAP Environment and
• to extend an existing RAP Business Object using the ABAP Cloud programming model.

You need the latest version of the ABAP Development Tools for Eclipse (ADT) on your laptop or PC as well as the access to an appropriate ABAP system* to carry out the practical exercises of this workshop.

(*) The supported ABAP systems are SAP BTP ABAP Environment, SAP S/4HANA Cloud, Public Edition or release 2023 (or higher) of SAP S/4HANA and SAP S/4HANA Cloud, Private Edition. The openSource RAP Generator must be imported into the relevant system - e.g. SAP BTP ABAP Environment Trial.

In the Getting Started section you will generate

• two exercise packages and
• an extensible managed Business Object (BO) with one entity Shop with generic transactional behavior - i.e. CRUD: Create, Read, Update, and Delete.

In Exercise 1 you will learn how to leverage the released RAP BO I_BankTP in your own code.

In Exercise 2.1 you will extend the behavior of the base RAP business object that has been generated at the end of the Getting Started section. You will learn how extend the behavior of the base RAP BEO by validations, determinations and side effects.

In Exercise 2.2 you will then continue to extend the data model with additional fields. This requires you to perform several steps and you have to create quite a lot of repository objects. (There is a plan to provide a Generator for that.)

In Exercise 2.3 you will continue to extend the behavior of the base RAP business object by adding an action. Since actions can only added via an extension to fields that have been added via an extension as well, adding an action via an extension must be performed after Exercise 2.2.

So let us start and have a look at the Getting Started section.

• Getting Started - Generate starter package
• Exercise 1 - Consume a released RAP BO
• Exercies 2 - Extend a RAP Business object
  • Exercise 2.1 - Extend the behavior (determinations, validations, side-effects)
  • Exercise 2.2 - Extend the data model (add additional fields)
  • Exercise 2.3 - Extend the behavior (add an action)

The packages ZRAP630_SOL and ZRAP630_SOL_EXT that contain the solutions of this workshop can be downloaded via abapGIT into an SAP BTP, ABAP Environment system or into the SAP S/4HANA Cloud, ABAP environment system.

Please note that these packages have already been installed in the SAP BTP, ABAP Environment Trial systems !
So there is no need to install them on an ABAP Environment trial system.
