Work in this lesson converts Core Data Services, Domain Models, Associations, Services, and Business Logic into a repeatable SAP practice. The scenario uses a development team extending an SAP application without modifying the digital core and supports the broader objective to develop side-by-side SAP BTP extensions using CAP and clean-core principles.
The instructor traces an end-to-end case involving a development team extending an SAP application without modifying the digital core. The demonstration explains system navigation, configuration dependencies, transaction results, and the evidence recorded in CDS data model and service definition. It also tests the exception where an association exposes unintended business data.
Complete a controlled exercise for Core Data Services, Domain Models, Associations, Services, and Business Logic. Confirm the business or technical objective, perform the required SAP steps, capture results, investigate the stated exception, and preserve the final outcome in CDS data model and service definition.
Begin where expected SAP behavior first differs from the observed result. Check organizational assignments, master data, configuration sequence, authorization, integration, and transaction evidence separately. Treat “an association exposes unintended business data” as a hypothesis until the relevant settings, logs, documents, and process outcomes confirm the cause.
Learners can perform Core Data Services, Domain Models, Associations, Services, and Business Logic, explain the system behavior, and defend the result through CDS data model and service definition.
