White Paper: Overview of SAP S/4HANA Cloud Extensibility

SAP has provided tools to achieve extensibility, both within the S/4HANA Cloud system (in-app) and when there is a need to connect S/4HANA Cloud to external systems (side-by-side).

In-App Extensibility: This concept covers the extension of standard applications in the capacity that includes:

  • Custom Fields
  • Custom Forms
  • Email Templates
  • Creation and Addition of Custom Business Logic
  • Creation of Custom Queries
  • Reusable Libraries for UI Elements and Code

Side-by-Side Extensibility: This is a concept whereby external systems can be integrated into SAP S/4HANA Cloud using SAP Cloud Platform. These external systems could support functions like IoT, Big Data Services, Process Innovations, Data Science, Cloud Native for B2B and B2C businesses, etc. Side-by-Side Extensibility includes the following functions:

  • Develop Custom Applications
  • Create Dependent Extensions
  • Consume Third-Party Apps
  • User Interface Integration
  • User Integration
  • Rules and Workflows, Events Integration
  • Process Integration and Data Replication

This white paper offers an overview of SAP S/4HANA Cloud Extensibility, including architecture, tools and features. It also provides a decision matrix to help you understand the different extensibility components for In-App Extensibility and Side-by-Side Extensibility in SAP S/4HANA.
