Participants work through Events, Friends, Exceptions, and Object Collaboration to coordinate object behavior and recover predictably from failures. The activity is grounded in an SAP development team refactoring procedural custom code into reusable services with clear responsibilities, testable behavior, controlled exceptions, and extensible designs and contributes directly to extensible ABAP objects.
The guided walkthrough links Instance and static events, Event handler registration, Class-based exceptions, Collaborating object patterns to business outcomes and control evidence. Learners see how the process should appear in SAP, what belongs in object collaboration exercise workbook, and how the team should respond when an event handler remains registered after its consumer should be released.
Complete a controlled activity covering Instance and static events, Event handler registration, Class-based exceptions, Collaborating object patterns and preserve the final result in object collaboration exercise 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 “an event handler remains registered after its consumer should be released” as a testable hypothesis until settings, documents, logs, reports, and retest outcomes confirm the cause.
Learners can apply Events, Friends, Exceptions, and Object Collaboration, explain the resulting SAP behavior, and defend the outcome through object collaboration exercise workbook.
