How does SAP BTP enable businesses to extend their existing SAP applications?

A fundamental principle of modernizing the SAP ecosystem is the concept of a "Clean Core." SAP BTP enables this by allowing organizations to build extensions "side-by-side" rather than within the core ERP code (classic "in-app" customization). By providing low-code/no-code development tools, such as SAP Build, the platform empowers both professional developers and "citizen developers" (business users with limited coding knowledge) to create applications that add specific business value without compromising the stability or upgradeability of the core SAP S/4HANA system.

These tools allow for the rapid creation of user interfaces using SAP Fiori elements and the automation of manual tasks through visual drag-and-drop interfaces. This approach is a stark contrast to traditional development, which often required extensive, custom ABAP coding that made system upgrades difficult and expensive. By positioning BTP as the extension layer, SAP ensures that businesses can remain agile and respond quickly to market changes. This flexibility is supported by a robust set of services that facilitate secure communication between the extension and the core system via APIs. Consequently, businesses can innovate at the edge while maintaining a stable, standardized digital core, which is the hallmark of the SAP Business Suite’s evolution into the cloud era.
