So, before we think about security, we need to understand the implemented use cases in the customer context. In this conjunction, the term “Clean Core” often comes up. The “Clean Core” approach is nothing new and was declared a buzzword in 2021. However, it is now gaining relevance because SAP BTP offers customers the desired flexibility due to its proximity and simplicity.
The term “Clean Core” describes nothing more than the decoupling and implementation of custom code and customer-specific solution extensions with minimal dependencies on the S4/ECC solution. In theory, this solves the problem of upgrade efforts concerning refactoring custom developments.
In summary, the Business Technology Platform intends to carve out customer enhancements to introduce a clear separation to the S/4HANA product. This promises more flexibility and expandability and at the same time, targets to reduce the effort required for SAP upgrades.
