SAP / SAP Mid Level (3 to 8 yrs) Interview questions
What is the difference between RAP and CAP?
Both are SAP's modern application development models, sharing CDS-based data modeling as a conceptual foundation, but they target different runtime environments and technology stacks.
| RAP | CAP |
| ABAP-based; runs on SAP's ABAP application server (on-premise or BTP ABAP Environment). | Node.js/Java-based; runs on SAP BTP's Cloud Foundry/Kyma environments. |
| Natural fit for extending existing ABAP/S/4HANA systems. | Natural fit for greenfield, cloud-native applications and services. |
| Business logic in ABAP behavior implementations. | Business logic in JavaScript/Java service handlers. |
The choice between them typically comes down to context: an organization extending an existing S/4HANA system with ABAP skills in-house often reaches for RAP, while a genuinely new, cloud-native microservice-style application, especially one built by teams already comfortable with Node.js/Java, more naturally fits CAP.
What runtime environment does RAP target, compared to CAP?
What context typically favors choosing RAP over CAP?
