SAP C_BW4H_214 Dumps Questions Answers

The feature of generating an external SAP HANA view is used to expose SAP BW/4HANA objects as SAP HANA calculation views, which can be consumed by other SAP HANA tools or applications. The following SAP BW/4HANA objects support this feature:

•Open ODS view, which is a flexible object that can be created on top of any source system and can be used as a source for other objects such as CompositeProviders or BW queries. An Open ODS view can have an external SAP HANA view generated automatically during activation or manually using the context menu option Generate External SAP HANA View.

•Composite Provider, which is a powerful object that can combine data from different InfoProviders using join or union operations. A Composite Provider can have an external SAP HANA view generated automatically during activation or manually using the context menu option Generate External SAP HANA View.

•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.
