C_BW4H_211 Exam Dumps - SAP Certified Application Associate - Reporting, Modeling and Data Acquisition with SAP BW/4HANA

Separating master data from transactional data in SAP BW/4HANA has the following benefits:

• It allows different data load frequency for master data and transactional data, which can improve the performance and flexibility of data loading processes. For example, master data can be loaded daily or weekly, while transactional data can be loaded hourly or near real-time.
• It ensures referential integrity on your transactional data by using SID values that link the transactional data to the master data. This way, the transactional data can be consistent and accurate across different InfoProviders and queries.
• It provides language dependent master data texts that can be displayed in different languages according to the user’s preference. This way, the master data can be more user-friendly and understandable for different audiences.

Open ODS views are used to associate an InfoObject with a characteristic hierarchy without changing the existing data flow. Open ODS views 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. Open ODS views can also leverage the LSA++ concept by using different layers such as staging, quality, and harmonization. References: 12

•C. Characteristic value: This type of variable can use the SAP HANA Exit processing type to determine default values for variables using an AMDP class implementation. This can improve the performance and flexibility of queries that are generated as external SAP HANA views12.

•D. Hierarchy node: This type of variable can use the SAP HANA Exit processing type to determine default values for variables using an AMDP class implementation. This can improve the performance and flexibility of queries that are generated as external SAP HANA views12.
