Introduction


Extensibility / flexibility covers a broad spectrum of topics that allows customers to adopt standard business software to their business needs. The spectrum spans topics from business configuration, UI/forms/report layout adoption, custom fields, objects and logic, integration, custom terminology and translation to customer-specific help.

Tutorial


In order to get familiar with the functionalities you can go through the following tutorials, which is intended for extensibility developers at customer as well as partner side.

Prerequisites

 

Authorization


To be able to work with extensibility apps your user needs business roles that are authorized for the corresponding business catalogs


Business Catalog Name Business Catalog ID Description Supported Applications

Custom Reusable Elements

Custom Logic Tracing
Extensibility - Custom Fields
SAP_CORE_BC_EXT_FLD

Tutorial Parts for Custom Solution Extensions

 

Create custom business objects (former parts I to II)


This tutorial group shows you how to build a simple custom application as a key user in S/4HANA Cloud using ABAP extensibility. Create a custom business object structure and persistence, then generate a UI to be exposed as a SAP Fiori Launchpad application, and finally implement logic to control the application. You will also see how to generally adapt SAP Fiori user interfaces.

Part III: Custom Code List (Bonus Plan)


Learn how to create and make use of a Custom Code List data type.
In the example a release status code list is created and used in bonus plan UI and Logic.

Part IV: Associated Business Objects (Bonus Entitlement with - Plan & Sales Order)


Learn how to let a second Custom Business Object work with the first and a standard Business Object.
In the example a manager wants to create a Bonus Entitlement (= bonus calculation) based on sales volume.

Part V: Custom Fields (Product)


Learn how to create Custom Fields at a standard business object and add them to its UI.
In the example a product manager wants to maintain a bonus percentage and validity period at the product to increase its sale.

As there are two ways to create custom fields, the tutorial shows both separately.

Part V: (A) Custom Field – via extensible Application (Product)

This way is easier, if you have no information about the business context and data source of the UI you want to add a field to initially.

Part V: (B) Custom Field (Product) – via Extensibility Application

This way is faster, if you know business context and UI data source, especially, if you want to create several fields. If you want to add a custom field to several UIs you only can enable them for all in the explicit extensibility application.

Part VI: Product @ Bonus Plan


Learn how to deepen the structure of a custom business object by creating a sub node.
In the example a manager wants to define a list of bonus relevant products at the Bonus Plan.

Part VII: Custom Fields – Logic


Learn how to use custom fields by reading their data.
In the example the Bonus Entitlement is enhanced by calculating an additional bonus for relevant sold products (percentage of the sales volume for them)

Part VIII: Custom Business Object exposure as External Web Service (Bonus Plan)


Learn how to expose a custom business object as web service for integration of a solution with other systems.
In the example all Bonus Plan data shall be exported to an Excel file.

Execute an Outbound Service from Custom Business Object Logic


Learn how to call an external service of SAP API Business Hub from inside the logic implementation of a custom business object.
In the example the Bonus Entitlement will be enhanced by a feedback functionality. The manager’s feedback will be translated automatically into English by calling the externally available service "Machine Translation API" of SAP.

Create Custom UI for S/4HANA Cloud


This tutorial group shows you how to create a simple custom UI for S/4HANA Cloud using SAP Business Technology Platform's SAP Business Application Studio. This side-by-side approach gives you more possibilities than the in-app generated UI from the very first tutorial group on top.
First you will learn how to set up your SAP Business Technology Platform Subaccount for SAP Business Application Studio including configuration on SAP Identity Authorization Service. Then your S/4HANA Cloud system and that subaccount will get connected to build a custom UI in SAP Business Application Studio. That custom UI will get deployed to S/4HANA Cloud and finally made available as new application there.

Some restrictions apply for SAP S/4HANA and SAP S/4HANA Cloud, private edition when developing a UI for a Custom Business Object. This blog shows how to handle these restrictions and complement the tutorial group (listed in the item before) in SAP S/4HANA and SAP S/4HANA Cloud, private edition since release 2022.
