Integration Testing in the context of an SAP project, as defined by the SAP Activate methodology, focuses on verifying that different components and systems work together as a cohesive unit. Its scope primarily includes two key areas: first, testing the interfaces and data exchange between the SAP system and other applications (both SAP and non-SAP) to ensure they communicate correctly. Second, it involves validating the functionality of end-to-end business processes that span multiple modules within the SAP system (e.g., Order-to-Cash, Procure-to-Pay) to confirm that transactions flow correctly from start to finish across the integrated landscape.

B. Connectivity between database and application servers: This is a low-level technical infrastructure test, typically conducted during the system build and verification phase, not as part of business process integration testing.

C. Quality of data for migration: This is the specific objective of Data Migration Testing, a separate testing stream focused on validating the accuracy and completeness of the data conversion process.

1. SAP Activate Roadmap Viewer: In the SAP Activate Methodology for SAP S/4HANA Cloud

public edition

the "Realize" phase includes the "Solution Test" deliverable. Within this

the task "Execute End-to-End Business Process (including integration) Tests" explicitly defines the testing of cross-modular business scenarios as a core activity. This directly supports option D.

2. SAP Activate Roadmap Viewer: The same "Solution Test" deliverable also contains the task "Execute Integration Test for Third-Party Integrations". This task's purpose is to "test the integration scenarios between SAP S/4HANA Cloud and the third-party solutions

" which directly supports option A.

3. SAP Help Portal - Test Management in SAP Solution Manager 7.2: The documentation on Test Scope Definition outlines that Integration Tests are designed to "check whether the components of your solution... work together as defined in the business process design." This encompasses both internal components (end-to-end processes) and external interfaces. (Reference: SAP Help Portal
