SAP Extensibility enables customers to adopt business specific customization and enhancements to the standard solution offered by SAP. Earlier SAP offered classic ABAP enhancement technique to enhance standard solution and is very powerful and flexible, as Classic extensibility allowed ABAP developers to use and even to modify SAP objects.

Challenge with classic extensions is missing clear interface between SAP code and extensions adds a lot of customer specific test and adaptation effort during SAP upgrades.

With Transition to S/4 HANA, an intelligent ERP solution available in the cloud and on-Premise, The goal is to move from classic ABAP Extensions to an SAP S/4 HANA extensibility model that allows customers to consume SAP innovations smoothly, leading to future-proof extensions that are ready for the next cloud transformation.

In the S/4 HANA cloud, there are no customer specific upgrade projects. Instead automated software updates run for all customers in parallel through Cloud First approach. Therefore, classical extensibility based on classical custom ABAP code can no longer be used.

SAP S/4 HANA cloud public edition provides a new upgrade-stable cloud extensibility model that clearly separates SAP code and extensions via mandatory public APIs and SAP Extension Points. It offers two extensions scenarios;

1. On-Stack extensions that run on SAP S/4 HANA cloud stack and are tightly coupled with S/4 HANA cloud data, transactions and applications like Key User Extensions, Developer extensibility.
2. Side-by-side extensions that run on SAP BTP and are loosely coupled extension scenarios integrating with S/4 HANA like SAP BUILD, SAP BUILD Process Automation, JAVA Node js applications on BTP.
