1. How would you describe Core Data Services (CDS) views to a non-technical business user?
Ans:
Custom CDS views act as a foundational building block for high-performance data modeling in SAP S/4HANA. They push data-intensive logic down directly to the database layer, minimizing duplicate information and streamlining enterprise analytics and corporate reporting frameworks.
2. What should an SAP ABAP consultant know about the transition from ECC to S/4HANA?
Ans:
An SAP ABAP consultant should understand modern S/4HANA architectures, the ABAP RESTful Application Programming Model (RAP), ABAP Cloud principles, custom code remediation, Fiori integration, and embedded analytics. Proficiency in code optimization, syntax adaptations, and performance tracing is also essential.
3. How would you analyze a new technical development requirement raised by a business team?
Ans:
I would start by understanding the existing workflow and the core business objective behind the request. I would document the requirement, check available standard SAP functionality and released APIs, assess configuration possibilities and integration dependencies, and evaluate testing and maintenance impacts before recommending a solution.
4. What does the clean-core development approach mean in an S/4HANA implementation?
Ans:
Clean core means keeping the standard SAP system untouched by modifications while utilizing upgrade-stable, cloud-ready side-by-side extensions. This approach reduces unnecessary technical debt, simplifies system maintenance, and supports smoother software upgrades and future innovations.
5. In what ways can SAP Fiori and modern UI extensions enhance technical user experience?
Ans:
SAP Fiori provides intuitive, role-based applications that allow users to complete tasks, monitor real-time data processes, and access analytical insights through clean interfaces. Developers utilize OData services and UI annotations to deliver streamlined user experiences aligned with specific corporate responsibilities.
6. What steps would you follow when troubleshooting a runtime error or short dump in ABAP programs?
Ans:
I would review the short dump via transaction ST22 to identify the error code, failing program statement, and active call stack. Then I would examine the underlying data structures, source code logic, database locks, or authorization settings. After pinpointing the root cause, I would apply the necessary fix, retest the script, and confirm stable execution.
7. Why is automation becoming critical in SAP ABAP development and testing?
Ans:
Automation helps minimize repetitive manual tasks such as code quality scans, unit testing, transport deployment, and regression checks. Modern development environments combine automated testing tools, ABAP Test Cockpit (ATC), and CI/CD pipelines to boost productivity while maintaining robust technical standards.
8. How would you test an end-to-end custom SAP ABAP development scenario?
Ans:
I would define the technical test scenario, verify required master data and custom database setups, execute the complete code workflow, verify database transactions, review output logs, and reconcile results against expected technical values. Any software defects found would be documented, debugged, and re-evaluated.
9. Which performance profiling capabilities are useful for an S/4HANA ABAP consultant?
Ans:
A consultant should understand database tracing (ST05), ABAP runtime analysis (SE30/SAT), SQL performance tuning, Code Inspector checks, and ATC analysis. These tools help evaluate execution time, runtime bottlenecks, and database load to optimize overall application performance.
10. What would you do if standard SAP functionality or released APIs do not completely satisfy a technical requirement?
Ans:
I would first re-validate the business requirement and explore alternative standard extension points or BAdIs. If custom development is unavoidable, I would implement an upgrade-safe solution following clean-core guidelines, ensuring appropriate security, performance tuning, and thorough maintenance planning.
