Learners examine configuration and operational behavior for ABAP SQL, CDS Views, Database Access, Filtering, and Performance Awareness. The work is grounded in a development team building its first controlled ABAP application while following modern language rules, database-efficient patterns, object orientation, testing, and transport discipline and contributes directly to maintainable foundational ABAP development.
The guided walkthrough connects ABAP SQL, CDS views, database filtering, performance-aware access to the intended business outcome and control evidence. Learners see the expected SAP behavior, what belongs in ABAP data-access and performance register, and how to respond when a database query returns duplicate records because the join condition is incomplete.
Complete a controlled activity covering ABAP SQL, CDS views, database filtering, performance-aware access and preserve the result in ABAP data-access and performance register.
Start at the earliest point where expected behavior differs from the observed result. Review process sequence, relevant data, configuration, authorization, integration, and timing as separate hypotheses. Treat “a database query returns duplicate records because the join condition is incomplete” as unconfirmed until settings, documents, logs, reports, and focused retesting support the cause.
Learners can apply ABAP SQL, CDS Views, Database Access, Filtering, and Performance Awareness, explain the resulting SAP behavior, and defend the outcome through ABAP data-access and performance register.
