This lesson develops controlled execution of CDS Data Definitions, Associations, and Expressions. The work is grounded in an ABAP development team modernizing reusable data models for transactional applications, analytical consumption, and secure service exposure and contributes directly to maintainable ABAP data models.
Using the scenario, the instructor demonstrates CDS view entities, associations and path expressions, joins and set operations, calculated elements and highlights object relationships, determination behavior, integration effects, and approval evidence. The demonstration deliberately introduces the exception where an association multiplies records because its cardinality does not match the underlying relationship.
Complete a controlled activity covering CDS view entities, associations and path expressions, joins and set operations, calculated elements and preserve the result in CDS entity and association evidence pack.
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 “an association multiplies records because its cardinality does not match the underlying relationship” as unconfirmed until settings, documents, logs, reports, and focused retesting support the cause.
Learners can apply CDS Data Definitions, Associations, and Expressions, explain the resulting SAP behavior, and defend the outcome through CDS entity and association evidence pack.
