Which are purposes of the Open Operational Data Store layer in the layered scalable architecture...

[: In SAP BW/4HANA, the Open ODS layer supports harmonization by providing tools like transformations and mappings to ensure consistency across data from disparate sources. This is particularly important in heterogeneous landscapes where data integration is a challenge., C. Initial staging of source system data, The Open ODS layer serves as an initial staging area for raw data extracted from source systems. It provides a temporary storage point where data can be landed and prepared for further processing or analysis., This staging capability ensures that data is available in its original form (or minimally transformed) for downstream processes, such as loading into other layers of the LSA++ architecture or enabling real-time reporting., Reference: The Open ODS layer is optimized for high-performance data ingestion and staging, making it ideal for scenarios where data needs to be quickly loaded and made available for operational reporting or further transformation., , Incorrect Options:B. Transformations of data based on business logic, While transformations can occur in the Open ODS layer, this is not its primary purpose. The Open ODS layer focuses on initial data staging and harmonization rather than complex business logic transformations., Business logic transformations are typically performed in subsequent layers of the LSA++ architecture, such as theData Propagation Layer (DPL)or theCore Data Warehouse Layer (CDWH)., Reference: SAP recommends keeping the Open ODS layer lightweight and focused on operational and near-real-time use cases, avoiding heavy transformations that could impact performance., D. Real-time reporting on source system data without staging, The Open ODS layer does support real-time reporting, but it requires data to be staged first. The layer acts as an intermediate storage point where data is landed and processed before being made available for reporting., Reporting directly on source system data without staging is typically achieved throughVirtual Data Models (VDMs)orSAP HANA Live, which bypass the need for staging entirely., Reference: The Open ODS layer is not designed for direct, real-time access to source system data without staging. Its role is to stage and prepare data for operational reporting or further processing., , Conclusion:TheOpen ODS layerin SAP BW/4HANA's LSA++ architecture is primarily used forharmonizing data from multiple source systemsand serving as aninitial staging area for source system data. These purposes align with its role in supporting operational and near-real-time reporting while maintaining flexibility and performance. The correct answers are thereforeAandC., , ]
