SAP ABAP Interview Questions and Evaluation Guide
Knowing ABAP syntax isn't enough to call someone a strong SAP developer. Good ABAP developers understand the Data Dictionary, reporting tools, enhancement techniques, object-oriented ABAP, performance tuning, and integration with the wider SAP landscape.
This guide gives you 40 SAP ABAP interview questions for junior, mid-level, and senior hiring, organized by skill area and experience level, plus a ready-to-use scorecard so every interviewer rates candidates against the same criteria.
What to Evaluate in an SAP ABAP Interview
Ten skill areas cover what separates a candidate who knows ABAP syntax from one who can actually ship reliable SAP solutions.
| Skill Area | What to Assess |
|---|---|
| ABAP Fundamentals | Syntax, internal tables, data types, control structures, code quality |
| Data Dictionary | Tables, structures, domains, data elements, views, search helps |
| Reports | Classical and interactive reports, ALV, selection screens |
| Dialog Programming | Module pool, screen flow logic, table controls |
| Enhancements | User exits, customer exits, BAdIs, enhancement framework |
| Object-Oriented ABAP | Classes, interfaces, inheritance, polymorphism, encapsulation |
| Performance and Debugging | SQL tuning, runtime analysis, debugger, dumps and logs |
| Integration | RFC, BAPI, IDoc, OData, and web services |
| Problem Solving | Diagnosing production issues, weighing upgrade-safe options |
| Communication | Documentation, functional-to-technical translation, code reviews |

Questions by Experience Level
Same topics, different depth. Adjust what you ask based on seniority.
Junior SAP ABAP questions: Foundations first
ABAP syntax, internal tables, basic reports, Data Dictionary, SE38/SE11 usage, basic debugging
- What is the difference between a report and a transaction?
- How do you declare and populate an internal table?
- What is the SE11 transaction used for?
- How do you write a simple SELECT statement with a WHERE clause?
- How do you set a breakpoint and step through code?
- What is the difference between a data element and a domain?
- How do you display data using WRITE statements?
Mid-level SAP ABAP questions: Independent delivery
Module pool, ALV programming, BAdIs and enhancements, OOP ABAP basics, performance fundamentals
- How would you build an ALV report with custom sorting and totals?
- How do you implement a BAdI for a standard business process?
- How would you validate data on a module pool screen?
- What steps would you take to debug a performance issue in a report?
- How do you use classes to structure reusable business logic?
- How would you handle error messages on a selection screen?
- What is your approach to testing custom enhancements before transport?
Senior SAP ABAP questions: System and team level
Enhancement strategy, integration (RFC, BAPI, IDoc, OData), performance tuning at scale, S/4HANA and CDS migration, mentorship
- How would you design an integration between SAP and a third-party system?
- How do you decide between enhancement techniques for a complex requirement?
- How would you approach migrating custom reports to CDS views in S/4HANA?
- How do you mentor junior developers on writing upgrade-safe code?
- How would you improve performance across a suite of poorly performing reports?
- How do you evaluate whether custom code should be replaced by standard SAP functionality?
- How do you structure code reviews for a team of ABAP developers?
SAP ABAP Interview Scorecard
Use this so every interviewer scores candidates against the same criteria instead of relying on gut feel.
| Evaluation Area | Weight | What Good Looks Like |
|---|---|---|
| ABAP Language and Code Quality | 15% | Writes clean, efficient, maintainable ABAP |
| Data Dictionary and Database Design | 10% | Understands tables, domains, data elements, and views |
| Reports and ALV Development | 15% | Builds efficient reports with good selection screen design |
| Enhancements and Customization | 15% | Chooses upgrade-safe enhancement techniques appropriately |
| Object-Oriented ABAP | 10% | Applies classes, interfaces, and encapsulation sensibly |
| Performance and Debugging | 15% | Diagnoses issues systematically using the right tools |
| Integration and Interfaces | 10% | Understands RFC, BAPI, IDoc, and web service patterns |
| Communication and Documentation | 10% | Explains technical decisions clearly, documents changes well |
| Rating | Meaning |
|---|---|
| 1 · Weak | Cannot explain core ABAP concepts or apply them reliably |
| 2 · Below Expected | Knows some fundamentals but struggles applying them |
| 3 · Meets Expectations | Sound working knowledge, can contribute independently |
| 4 · Strong | Depth, judgment, clear problem-solving, reliable ownership |
| 5 · Exceptional | Expert-level depth, system thinking, strong technical leadership |
What Strong SAP ABAP Candidates Demonstrate
Look for candidates who can:
- Explain internal table types and choose the right one for the job
- Write efficient SELECT statements and avoid database calls inside loops
- Choose enhancement techniques based on upgrade safety, not convenience
- Apply object-oriented ABAP where it genuinely improves maintainability
- Debug systematically using the right transaction for the right problem
- Understand how ABAP fits into the wider SAP integration landscape
- Explain technical trade-offs in language functional teams can understand
For senior roles, go deeper on enhancement strategy, performance at scale, integration architecture, and mentorship.

- A recorded, transcribed interview for later review
- A consistent process across internal and external interviewers
Frequently Asked Questions
Common questions from hiring teams building an Android interview process.
Enough to assess the role without turning the interview into a checklist. Most structured interviews work well with 20 to 30 targeted questions across fundamentals, Data Dictionary, reports, enhancements, and scenario-based problem-solving.
No. Syntax matters, but ABAP developers also need to be evaluated on Data Dictionary design, enhancement strategy, performance tuning, debugging discipline, and integration knowledge.
Most production systems still run a mix of classical ABAP and newer S/4HANA constructs. Strong candidates should be comfortable with both and understand when to apply each.
Ask about enhancement strategy, performance tuning at scale, integration architecture, migration to S/4HANA and CDS views, and mentoring junior developers.
Yes, adjust the depth. Junior interviews should focus on fundamentals and practical implementation. Senior interviews should weigh enhancement strategy, performance, integration, and technical leadership more heavily.
