When a customer has unique business requirements that are not fully catered by standard SAP S/4HANA then there is a need to extend the system. These extensions can be classified into two broad categories:
On-stack extensibility involves extending SAP S/4HANA directly within the core system using key user tools or ABAP.
Side-by-side extensibility uses SAP Business Technology Platform (BTP) to develop custom applications or integrations outside the core S/4HANA system, ensuring greater flexibility and upgrade safety.
How to extend and personalize SAP applications
A new Extensibility wizard is available with SAP S/4HANA Cloud Public Edition 2408 that provides both on-stack and side-by-side extension options consolidated into a single wizard.
It provides a guided experience to kick start extension creation and enables seamless navigation from SAP S/4HANA to SAP Build.
The wizard understands which S/4HANA application it has been started from and accordingly filters the extensions points (like API, Events) based on the business context.
This wizard can be accessed from any extensible SAP S/4HANA app as shown below.
