Given that standard SAP software cannot encompass all business processes, there is an ongoing need for new apps, reports, and functionalities. Traditionally, SAP partners and customers have built extensions on the SAP ECC system using ABAP code. However, with SAP S/4HANA and the customer's digital transformation journey towards the cloud, a more robust and loosely coupled extensibility model is required.
The Clean Core Paradigm
The clean core paradigm separates extensions from the core SAP app and connects to business objects through stable interfaces. This approach ensures smooth upgrades and extensions, preventing issues when moving from SAP S/4HANA on-premise to the Cloud. SAP aims to help customers expand their software with seamless updates using this concept.
By embracing the clean core paradigm, you can enjoy benefits like lower TCO, streamlined upgrades, less testing for users, and minimal adaptation for developers. It also enables IT providers to offer fixed-price upgrades, boosts innovation speed, accelerates SAP-delivered innovation adoption, supports quick response to changing business needs, and prepares organizations for cloud migration concerning custom extensions.
