Who it's for: Backend developers building side-by-side extensions to SAP applications — especially SAP S/4HANA Cloud — on SAP BTP who want a recognized associate credential proving they can design and run CAP applications using Node.js/JavaScript, Java, Core Data Services, and SAP Fiori elements, while also mentoring others on the team.
The SAP® C_CPE certification checks whether you can actually design and build extension applications with the SAP Cloud Application Programming Model (CAP), not merely talk about them. It centers on the side-by-side extensibility approach on SAP BTP, where a CAP service extends an existing SAP application such as SAP S/4HANA Cloud without modifying the core. The scope runs end to end: setting up a CAP project, modeling data and services with Core Data Services and the OData protocol, generating an SAP Fiori elements user interface, adding custom business logic and event handling, securing the app with authorization and trust management, consuming external services, deploying to the Cloud Foundry runtime, and integrating the result into SAP Build Work Zone. Because it is delivered as a System-Based Assessment with a single hands-on activity, the exam rewards applied execution in a working environment rather than isolated recall, and it targets a backend developer who can also guide teammates.
The blueprint areas to focus your preparation on.
Understanding why side-by-side extensibility matters, how CAP fits the SAP BTP Developer's Guide, and when an extension should live alongside the core SAP application — such as SAP S/4HANA Cloud — instead of modifying it, so your architectural choices match the recommended patterns.
Setting up a CAP project and defining its data model and services using Core Data Services, the OData protocol, and JSON/YAML descriptors, so that services expose the right entities and default behavior correctly across the end-to-end use case.
Generating and serving an SAP Fiori elements user interface on top of a CAP service, including local launch pages, so the extension presents a usable, annotation-driven front end without hand-coding the UI layer from scratch.
Adding custom code to a CAP service through the event-handling model, recognizing where standard behavior is insufficient, and implementing robust error handling so the extension enforces the required business rules reliably.
Securing a CAP application with authorization and trust management via XSUAA, defining CDS restrictions and roles, and consuming external services with the connectivity and extensibility features CAP provides — including writing and running unit tests to validate the integration.
Choosing among CAP deployment options, preparing and running the deployment to the SAP BTP Cloud Foundry runtime, and surfacing the finished extension inside SAP Build Work Zone so end users can reach it from a central launchpad.
Working across the SAP BTP Cloud Foundry and Kyma runtimes — application lifecycle, routing and networking, scaling and autoscaling, blue-green updates, plus Kubernetes and Kyma concepts such as workloads, services, eventing, and service management — to run and operate cloud-native extensions.
The SAP learning-journey courses this certification draws on.
Develop extensions with CAP following the SAP BTP Developer's Guide
The core course of the journey — walks through building a CAP application end to end while following the SAP BTP Developer's Guide, from project setup and CDS service modeling to Fiori elements UIs, custom logic, XSUAA authorization, external services, Cloud Foundry deployment, and Work Zone integration.
Develop cloud applications using SAP Business Application Studio
Shows how to build and deploy business applications in SAP Business Application Studio with its productivity tools, using a risk-management extension to SAP S/4HANA as the running example — covering data models, services, sample data, Fiori tooling, user roles, Git sharing, CI/CD, plus mobile UI and multitenancy.
