SAP C_BW4H_2404 SAP Certified Associate - Data Engineer - Data Fabric Exam Practice Test

•C. Accelerated SAP BW/4HANA implementation using ready-made models: This is an advantage of using SAP BW/4HANA business content. Business content provides a preconfigured set of application-specific information models based on consistent metadata in SAP BW/4HANA. It can be used without adjustment, be adjusted or enhanced by the customer, or serve as a template to help the customer create his own data models. This can speed up the implementation process and reduce the development effort12.

•D. Ability to combine business content objects with custom-defined objects: This is an advantage of using SAP BW/4HANA business content. Business content objects can be integrated with custom-defined objects using CompositeProviders or other modeling tools. This can enable flexible and agile data modeling and analysis according to the customer’s specific needs13.

•A. You cannot use navigation attributes for this characteristic: This is a disadvantage of setting the High Cardinality flag for a characteristic. A characteristic with high cardinality cannot be used as a navigation attribute for another characteristic, and therefore it cannot have navigation attributes itself12.

•C. SID numbers are created at runtime which might negatively affect the reporting performance: This is a disadvantage of setting the High Cardinality flag for a characteristic. A characteristic with high cardinality has no persistent SID values and no SID table, which means that the SID numbers are generated on the fly during query execution. This can have a negative impact on the reporting performance, especially if the characteristic is used in filters or aggregations13.

•A. Combine InfoProviders using Join and Unions: This is what a Composite Provider allows you to do in SAP BW/4HANA. A Composite Provider is an InfoProvider that combines data from several analytic indexes or from other InfoProviders (by union or inner join or left outer join), and makes this data available for reporting and analysis. Storing the data in BW Accelerator or in an SAP HANA database also ensures faster access to data in the query12.

•C. Define new restricted key figures: This is what a Composite Provider allows you to do in SAP BW/4HANA. A Composite Provider can define new restricted key figures based on the existing key figures of the underlying InfoProviders. Restricted key figures are key figures that are restricted by one or more characteristics13.

•E. Integrate SAP HANA HDI calculation views: This is what a Composite Provider allows you to do in SAP BW/4HANA. A Composite Provider can integrate SAP HANA HDI calculation views as part of its data sources, using a virtual table or an external SAP HANA view. This can enable mixed modeling scenarios that leverage both SAP BW/4HANA and SAP HANA capabilities14.

•A. Use fewer drill-down characteristics in the initial view: This can improve the query performance by reducing the amount of data that needs to be transferred and displayed at the start of the query execution. The user can drill down to more details later if needed1.

•D. Use mandatory characteristic value variables: This can improve the query performance by restricting the data selection to a smaller set of values that are relevant for the user. The user can also change the variable values later if needed1.

•E. Use include functions in the restricted key figures: This can improve the query performance by avoiding unnecessary calculations and aggregations that are done when using exclude functions. Include functions are also more efficient than selections or restricted key figures when filtering data1.

•A. Rank: This node type is only available for graphical modeling of SAP HANA HDI Calculation Views(XS Advanced), but not for SAP HANA Calculation Views(XS Classic). It allows you to rank the data based on a measure and a ranking rule12.

•D. Graph: This node type is only available for graphical modeling of SAP HANA HDI Calculation Views(XS Advanced), but not for SAP HANA Calculation Views(XS Classic). It allows you to model graph data and perform graph operations such as shortest path, neighborhood search, and pattern matching13.
