InSAP ERP, aGeneric DataSourceis used to extract data from various source types and make it available for consumption in SAP BW/4HANA or other systems. The source type defines the origin of the data and how it is extracted. Below is an explanation of the correct answers and why they are valid.
A. ABAP class method
AnABAP class methodcan be used as a source type for a Generic DataSource. This approach allows developers to encapsulate complex logic within an ABAP class and expose the data extraction logic through a specific method.
The method is called during the data extraction process, and its output is used as the data source. This is particularly useful for scenarios where custom logic or calculations are required to prepare the data.
[: SAP provides support for ABAP class methods as part of its Generic DataSource framework, enabling flexible and reusable data extraction., B. SAP query, AnSAP querycan also serve as a source type for a Generic DataSource. SAP queries are predefined reports created using the SAP Query tool, which allows users to extract data from logical databases or user-defined views., By leveraging SAP queries, non-technical users can create data sources without requiring extensive programming knowledge. The query output is then used as the basis for the Generic DataSource., Reference: SAP Query is a widely used tool in SAP ERP for creating ad-hoc reports and data extracts, making it a convenient option for Generic DataSources., D. ABAP function module, AnABAP function moduleis one of the most common source types for Generic DataSources. Function modules are reusable ABAP routines that encapsulate specific business logic or data extraction processes., During the extraction process, the function module is executed, and its output is passed to the Generic DataSource. This approach is highly flexible and supports complex data transformations and filtering., Reference: SAP BW/4HANA extensively uses ABAP function modules for data extraction, as they provide a robust and scalable way to retrieve data from SAP ERP systems., , Incorrect Options:C. ABAP managed database procedure, ABAP Managed Database Procedures (AMDPs)are used to execute database-specific logic directly on the database layer. While AMDPs are powerful for performance optimization, they are not supported as a source type for Generic DataSources., Generic DataSources rely on higher-level ABAP constructs like function modules or class methods rather than low-level database procedures., Reference: AMDPs are primarily used for advanced SQLScript-based processing and are not integrated into the Generic DataSource framework., E. Database view, Whiledatabase viewsare commonly used to structure and organize data in SAP ERP, they cannot be directly used as a source type for Generic DataSources. Instead, database views are typically accessed indirectly through ABAP function modules or class methods., Reference: SAP recommends using higher-level ABAP constructs (e.g., function modules) to encapsulate the logic for accessing database views, ensuring better flexibility and maintainability., , Conclusion:The correct answers areA. ABAP class method,B. SAP query, andD. ABAP function module, as these are the supported source types for creating Generic DataSources in SAP ERP. These options provide flexibility, reusability, and ease of use for extracting data from SAP ERP systems.]
