SAP ABAP on HANA — Lesson 3: AMDP, SQLScript, Table Functions, Procedures, Native Capabilities, and Exception Handling

Learning Objectives

• Explain the SAP structures, data, settings, roles, and dependencies governing AMDP and SQLScript implementation.
• Perform and validate table functions, procedures, and exception controls using reviewable system evidence.
• Evaluate the condition where a code-pushdown change runs faster but returns different results because client handling, null semantics, aggregation, authorization, and currency logic moved across layers and select proportionate corrective action.

Detailed Topics

• AMDP applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• SQLScript applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Table Functions applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Procedures applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Native Capabilities applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• and Exception Handling applied to the course scenario, expected SAP behavior, dependencies, and evidence.

Instructor Demonstration

The instructor traces an ABAP modernization team improving custom application performance while preserving functional correctness and maintainability. The walkthrough connects navigation, configuration or process logic, system messages, and evidence captured in the ABAP-on-HANA modernization, performance, and validation dossier. It also tests the exception where a code-pushdown change runs faster but returns different results because client handling, null semantics, aggregation, authorization, and currency logic moved across layers.

Hands-On Exercise

Complete a controlled SAP exercise covering AMDP, SQLScript, Table Functions, Procedures, Native Capabilities, and Exception Handling and preserve the verified result in the ABAP-on-HANA modernization, performance, and validation dossier.

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 AMDP and SQLScript implementation.
• Compare two defensible responses and explain business, technical, control, and support trade-offs.
• Determine how the ABAP-on-HANA modernization, performance, and validation dossier 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 code-pushdown change runs faster but returns different results because client handling, null semantics, aggregation, authorization, and currency logic moved across layers” 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-on-HANA modernization, performance, and validation dossier 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 AMDP, SQLScript, Table Functions, Procedures, Native Capabilities, and Exception Handling, explain the resulting SAP behavior, and defend the outcome through the ABAP-on-HANA modernization, performance, and validation dossier.
