SAP ABAP S/4HANA Backend Developer — Lesson 1: ABAP Development Tools, Language Foundations, ABAP SQL, Internal Tables, and CDS

Learning Objectives

• Explain the SAP structures, data, settings, roles, and dependencies governing ABAP language and Eclipse workflow.
• Perform and validate ABAP SQL, internal tables, and CDS using reviewable system evidence.
• Evaluate the condition where a custom application passes functional testing but creates performance and upgrade risk through unrestricted database access and modifications and select proportionate corrective action.

Detailed Topics

• ABAP Development Tools applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Language Foundations applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• ABAP SQL applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Internal Tables applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• and CDS applied to the course scenario, expected SAP behavior, dependencies, and evidence.

Instructor Demonstration

The instructor traces a development team building maintainable backend services and extensions for a large S/4HANA implementation. The walkthrough connects navigation, configuration or process logic, system messages, and evidence captured in the ABAP backend development, quality, and release portfolio. It also tests the exception where a custom application passes functional testing but creates performance and upgrade risk through unrestricted database access and modifications.

Hands-On Exercise

Complete a controlled SAP exercise covering ABAP Development Tools, Language Foundations, ABAP SQL, Internal Tables, and CDS and preserve the verified result in the ABAP backend development, quality, and release portfolio.

1. Confirm scope, prerequisites, master data, roles, dependencies, and acceptance criteria.
2. Execute the workflow while recording settings, transactions, outputs, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, and handover actions.

Scenario Analysis

• Identify which object, rule, setting, or process step most strongly influences ABAP language and Eclipse workflow.
• Compare two defensible responses and explain business, technical, control, and support trade-offs.
• Determine how the ABAP backend development, quality, and release portfolio should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected SAP behavior first differs from the observed result. Check master data, configuration sequence, authorization, integration, status, and transaction evidence separately. Treat “a custom application passes functional testing but creates performance and upgrade risk through unrestricted database access and modifications” as a hypothesis until system settings, logs, documents, and outcomes confirm the cause.

Validation Checklist

• Required SAP structures, master data, roles, settings, and dependencies are present.
• The ABAP backend development, quality, and release portfolio connects each conclusion to objective, reviewable evidence.
• Normal processing, the boundary condition, integration behavior, and exception were tested.
• Corrections, ownership, retest criteria, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply ABAP Development Tools, Language Foundations, ABAP SQL, Internal Tables, and CDS, explain the resulting SAP behavior, and defend the outcome through the ABAP backend development, quality, and release portfolio.
