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.
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.
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|
|Extensibility||SAP_CORE_BC_EXT||This business catalog enables you to create and maintain custom fields and custom logic, custom business objects, and custom CDS views.||Custom Business Objects, Custom Fields and Logic, Custom CDS Views, Custom Catalog Extensions, Custom Communication Scenarios|
|Software Collection Export||SAP_CORE_BC_SL_EXP||This business catalog enables you to add extension items to a software collection and export the software collection.||Manage Software Collection|
|Software Collection Import||SAP_CORE_BC_SL_IMP||Import Software Collection|
After having assigned your business roles with the right catalog authorizations you’ll have the needed applications on your Home Page within the Extensibility group.

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.
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.
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.
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.
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.
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.
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)
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.
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.
This tutorial group shows you how to create a simple custom UI for S/4HANA Cloud using SAP Cloud Platform’s SAP Web IDE. 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 Cloud Platform Neo Subaccount for SAP Web IDE including configuration on SAP Identity Authorization Service. Then your S/4HANA system and the that subaccount will get connected to build a custom UI in SAP Web IDE. That custom UI will get deployed to S/4HANA Cloud and finally made available as new application there.
