SAP ABAP Developer Skills and How to Assess Them

SAP ABAP (Advanced Business Application Programming) is SAP’s programming language for building reports, interfaces, enhancements and custom applications on SAP systems. An SAP ABAP developer extends standard SAP functionality to fit a company’s processes. Today the role also requires ABAP on HANA, CDS views and RAP skills for S/4HANA.

Hiring for these roles is tricky because SAP experience on a resume can mean ten years of classic report writing or two years of modern S/4HANA development. This guide explains the skills that matter and how Glider AI Technical Assessments help TA teams and SAP practice leads test them before interviews.

What does an SAP ABAP developer do?

An SAP ABAP developer writes and maintains the custom code that sits on top of standard SAP modules such as finance, sales, procurement and logistics. The work is usually split into a few recurring object types, often described with the acronym RICEFW.

  • Reports: ALV and classical reports that pull and display business data
  • Interfaces: data exchange through BAPIs, RFCs, IDocs and OData services
  • Conversions: data migration programs for go lives and system moves
  • Enhancements: user exits, BADIs and enhancement points that change standard behavior
  • Forms: SmartForms, SAPscript and Adobe Forms for invoices and documents
  • Workflows: automated approval and routing logic

Developers work closely with functional consultants, who translate business requirements into technical specifications.

Classic ABAP vs ABAP on HANA: what changed for hiring

Moving from SAP ECC to S/4HANA changed what a strong ABAP developer looks like.

AreaClassic ABAP (ECC)ABAP on HANA / S/4HANA
Data accessOpen SQL, logic in the application layerCode pushdown to the database with CDS views and AMDP
Programming modelProcedural reports, dialog programsABAP Objects, RAP (RESTful ABAP Programming model)
User interfaceSAP GUI screensSAP Fiori apps through OData services
ExtensibilityModifications and user exitsClean core extensions, BADIs, side by side extensions
Hiring signalReport and enhancement depthModern data modeling, Fiori integration, clean core thinking

Many companies run both. Be explicit in the job description about which landscape the hire will support, and test for that landscape.

Core SAP ABAP developer skills to screen for

Language fundamentals

  • ABAP syntax, internal tables, work areas and field symbols
  • ABAP Objects: classes, interfaces, inheritance and exception classes
  • Open SQL and performance aware database access
  • Debugging with the ABAP debugger and runtime analysis tools

Modern S/4HANA skills

  • Core Data Services (CDS) views and annotations
  • ABAP Managed Database Procedures (AMDP)
  • RAP for building transactional apps and services
  • OData service creation for SAP Fiori

Integration and enhancement

  • BAPIs, RFCs and IDocs for system integration
  • Enhancement framework: BADIs, user exits and implicit enhancements
  • Forms development in SmartForms or Adobe Forms

Working practices

  • Translating functional specs into clean technical designs
  • Transport management and change control
  • Code reviews and use of the ABAP Test Cockpit

How to assess SAP ABAP developer candidates

Certifications and project lists help, but they do not show how someone writes code. A practical assessment process looks like this.

  1. Define the landscape. ECC, S/4HANA, or both, plus the modules the developer will touch.
  2. Test fundamentals with a short knowledge check covering internal tables, ABAP Objects and SQL performance.
  3. Add scenario questions drawn from your environment, such as choosing between a BADI and a user exit, or redesigning a slow report with CDS views.
  4. Include a coding or code review task where the candidate fixes or improves a short ABAP program.
  5. Review results with the SAP practice lead before scheduling technical interviews.

Keep the test focused on the work the hire will do in the first six months.

How Glider AI helps

Glider AI Technical Assessments let TA teams and SAP practice leads build SAP ABAP developer tests from a library covering 250+ technologies, including enterprise software skills. You can mix multiple choice, scenario and open ended question types, and score answers against clear rubrics.

  • Role specific tests for ECC, S/4HANA or mixed landscapes
  • AI Proctoring that flags tab switching, copy and paste and other activity for review
  • Identity checks that confirm the person taking the test is the person you interview
  • Skill level reporting that shows where each candidate is strong or weak
  • ATS integration so results stay with the candidate profile

System integrators and staffing firms that place SAP consultants can also use the same tests across many requisitions; see Glider AI for staffing firms.

Frequently asked questions

What skills does an SAP ABAP developer need?

Core ABAP syntax, ABAP Objects, internal tables, Open SQL performance, debugging, and enhancement techniques like BADIs and user exits. For S/4HANA roles, add CDS views, AMDP, RAP and OData for Fiori.

What is the difference between ABAP and ABAP on HANA?

ABAP on HANA is the same language used with techniques that push data heavy logic down to the SAP HANA database, mainly through CDS views and AMDP. It requires a different approach to data modeling and performance than classic ABAP.

How do you test an SAP ABAP developer?

Combine a short knowledge check with scenario and coding questions drawn from your landscape. Score correctness and design choices, and use proctoring so results reflect the candidate’s own work.

Is SAP certification enough to hire an ABAP developer?

Certification shows baseline knowledge, but it does not show coding quality or problem solving. Pair it with a practical assessment and a review of past project work.

What is RICEFW in SAP ABAP?

RICEFW stands for Reports, Interfaces, Conversions, Enhancements, Forms and Workflows. It is a common way to categorize the custom development objects an ABAP developer builds.

Is ABAP still in demand with S/4HANA?

Yes. S/4HANA still runs on ABAP, and migrations create demand for developers who can modernize custom code, build CDS based data models and follow clean core extension practices.

Hire SAP ABAP developers on demonstrated skill

The right SAP ABAP developer protects your SAP investment and keeps custom code maintainable through upgrades. Use Glider AI Technical Assessments to test ABAP skills for ECC and S/4HANA roles with proctored, rubric scored results, and send only qualified candidates to your SAP leads.
