C_BW4H_2404 Exam Dumps - SAP Certified Associate Questions and Answers

A. To decrease memory consumption:

Delta merges move data from the delta storage to the main storage of SAP HANA. This optimizes memory usage by compressing and consolidating data.

D. To improve the read performance of InfoProviders:

By merging delta data with main storage, queries access fewer fragmented data structures, leading to better read performance.

References: SAP HANA Performance Optimization Guide (SAP Help Portal - Delta Merge).

SAP ECC (Answer B):

SAP ECC is supported as a legacy source system through the BW bridge, allowing seamless integration.

SAP S/4HANA (On-premise and Cloud) (Answers D, E):

Both on-premise and cloud versions of SAP S/4HANA are supported for modern business integration scenarios.

SAP Ariba (Option A):Not directly supported in BW bridge.

SAP SuccessFactors (Option C):Requires a separate integration mechanism outside BW bridge.

Incorrect Options:References:

Replace Lower-Level CompositeProvider (Answer A):

Using a DataStore object (advanced) for historical data improves performance by enabling optimized data storage, indexing, and query execution compared to a CompositeProvider.

Generate Dataflow for Historic Data (Answer D):

The "Generate Dataflow" feature allows you to extract data from Open ODS views and load it into new advanced DataStore objects, improving performance by reducing dependency on dynamic query processing.

Join Node Instead of Union (Option B):Joins are not suitable for comparing current and historic values.

Open ODS for Current Data (Option C):Open ODS views for current data may introduce latency and lack indexing optimizations.

A. RSECADMIN:

This transaction allows direct assignment of analysis authorizations to individual users for controlling access to data in SAP BW/4HANA.

D. PFCG with S_RS_AUTH:

Analysis authorizations can be assigned to roles via transaction PFCG using the authorization object S_RS_AUTH to integrate security roles effectively.

References:SAP BW/4HANA Analysis Authorization Management (SAP Help Portal).

Delta Merge in Process Chain (Answer A):

A dedicated process type can trigger delta merge during process chain execution.

This ensures consistent performance and data integrity for SAP HANA database tables.

Delta Merge via Data Load Monitor (Answer B):

The data load monitor offers an option to initiate the delta merge manually or monitor its status.

Useful for ensuring delta merges are applied after large data loads.

Flag in Transformation (Option C):No specific flag for delta merge exists at the transformation level.

Flag in Data Transfer Process (Option D):The data transfer process doesn’t control the delta merge.

Incorrect Options:References:

High Cardinality Flag:

This flag is used for characteristics with a very large number of distinct values, optimizing their performance.

Restrictions:

Navigation Attribute Usage (Answer A):Characteristics marked with high cardinality cannot act as navigation attributes for other characteristics.

Hierarchy Restriction (Answer D):These characteristics cannot be used as external characteristics in hierarchies.

Option B:Navigation attributes for this characteristic can still be used.

Option C:High cardinality supports more than 2 billion records.

Incorrect Options:References:

SAP BW/4HANA High Cardinality Characteristics Documentation

Single Start Process (Answer A):

A process chain can have only one start process, ensuring a clear entry point for execution.

Schedule Without Predecessor (Answer D):

The start process is unique in that it does not require a predecessor, allowing it to initiate the process chain directly.

Embedded in a Meta Chain (Option B):Any process can be embedded in a meta chain.

Successor Process (Option C):The start process cannot have a predecessor by design.

Explanation:

Snapshot Support in a DataStore object (advanced) retains historical data snapshots. While this feature enables detailed historical analysis, the data activation process is slower because it requires additional management of snapshots during activation.

References:SAP BW/4HANA DataStore Object Advanced Guide (SAP Help Portal).

A. DataStore object (advanced):

Used to persist data from the Open ODS View in SAP BW/4HANA.

C. Transformation:

Automatically generated to map and transform data from the Open ODS View to the DataStore object.

D. Data source:

Created to extract data from the SAP HANA database table into SAP BW/4HANA.

References:SAP BW/4HANA Open ODS View documentation (SAP Help Portal).

A. RSORBCT in SAP BW/4HANA system:

This transaction enables you to activate DataSources as part of BI Content in the SAP BW/4HANA system.

It handles content activation and transfer for reporting purposes.

B. RSA5 in SAP ERP system:

This transaction is used to install DataSources from the delivered Business Content in SAP ERP. It makes the DataSource available for extraction.
