This lesson applies Design Review, Unit Testing, Refactoring, and Handover within an SAP development team refactoring procedural custom code into reusable services with clear responsibilities, testable behavior, controlled exceptions, and extensible designs. Learners connect SAP behavior, business intent, and retained evidence while working toward extensible ABAP objects.
The instructor models an end-to-end decision path covering Object-oriented design review, ABAP Unit concepts, Dependency isolation, Refactoring and documentation. Navigation, documents, configuration influences, authorization boundaries, and retained evidence are connected to ABAP objects assurance and refactoring plan, including a controlled test where a refactoring passes unit tests but changes a required integration side effect.
Complete a controlled activity covering Object-oriented design review, ABAP Unit concepts, Dependency isolation, Refactoring and documentation and preserve the final result in ABAP objects assurance and refactoring plan.
Start at the earliest point where expected SAP behavior differs from the observed result. Review process sequence, master data, organizational assignments, configuration, authorization, integration, and timing separately. Treat “a refactoring passes unit tests but changes a required integration side effect” as a testable hypothesis until settings, documents, logs, reports, and retest outcomes confirm the cause.
Learners can apply Design Review, Unit Testing, Refactoring, and Handover, explain the resulting SAP behavior, and defend the outcome through ABAP objects assurance and refactoring plan.
