SAP S/4HANA Extensibility
Overview
Extensibility is a key capability of SAP ECC and SAP S/4HANA. It enables customers to customize their business processes and allows partners to enrich ERP with tailor-made solutions. This document provides an overview on the extensibility options and guidelines for ABAP based extensions on SAP S/4HANA in the cloud and on-premise for project managers, key users, and ABAP developers.
This is causing issues during upgrades and resulting a huge delay in the upgrade process. For example, if we use an SAP object that is not whitelisted by SAP, after an upgrade the used SAP Object might be changed or deleted. Now, we will have to adjust the extension thus upgrade is delayed.
Clean Core Paradigm
What
With an ERP clean core strategy, you can help ensure the organization benefits from the latest release with minimal modifications and cloud-compliant extensions and customizations.
Clean core is an extension methodology in which
- Extensions are kept strictly separate from the SAP application.
- Extensions access SAP business objects only through well defined, upgrade-stable interfaces.
Why
- Business Change
- New Technologies
- Landscape Complexity
By following clean core paradigm, we can be sure that
- Extensions do not break an upgrade and upgrades do not break an extension.
- Extensions do not create a problem when you migrate from SAP S/4HANA on-Premise to SAP S/4HANA Cloud.
Benefits
- Cloud Ready Application Development
- Simplifying Upgrades
- Reducing Development and Testing efforts
- Absorb innovation delivered by SAP at a faster rate
- React fast on changing business requirements and build cloud ready solutions.
Extensibility Model in SAP S/4HANA
SAP S/4HANA provides a new upgrade-stable cloud extensibility model that clearly separates SAP code and extensions via mandatory public SAP APIs and SAP extension points.
This cloud extensibility model consists of:
- Key-user extensibility
- Developer Extensibility (Embedded Steampunk)
- Side-by-side extensions on SAP BTP
In addition to above extensibility options SAP also provides classic extensions as well for On Premise solutions:
Detailed comparison across all the extensibility options is as follows:
SAP Key User Extensibility is subpart of larger SAPUI5 Flexibility Services which offers various ways in which standard delivered SAP fiori apps can be enhanced.
