The focus is Classes, Objects, Visibility, and Encapsulation, with practical decisions designed to model clear object responsibilities and protected state. Work is evaluated against the needs of an SAP development team refactoring procedural custom code into reusable services with clear responsibilities, testable behavior, controlled exceptions, and extensible designs.
The instructor traces Local and global classes, Attributes and methods, Constructors and object references, Visibility and encapsulation through the course scenario, explaining navigation, decision logic, dependencies, system messages, and the evidence retained in ABAP class design workbook. The walkthrough also shows how to investigate the condition where a public attribute allows callers to bypass required validation.
Complete a controlled activity covering Local and global classes, Attributes and methods, Constructors and object references, Visibility and encapsulation and preserve the final result in ABAP class design workbook.
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 public attribute allows callers to bypass required validation” as a testable hypothesis until settings, documents, logs, reports, and retest outcomes confirm the cause.
Learners can apply Classes, Objects, Visibility, and Encapsulation, explain the resulting SAP behavior, and defend the outcome through ABAP class design workbook.
