SAP C_BW4H_2404 - SAP Certified Associate - Data Engineer - Data Fabric
What are some of the benefits of using an InfoSource in a data flow? Note: There are 2 correct answers to this question.
Splitting a complex transformation into simple parts without storing intermediate data
Providing the delta extraction information of the source data
Enabling a data transfer process (DTP) to process multiple sequential transformations
Realizing direct access to source data without storing them
The Answer Is:
A, CExplanation:
An InfoSource in SAP BW/4HANA is a logical object used in data flows to facilitate the movement and transformation of data between source systems and target objects (e.g., DataStore Objects, InfoCubes). Let’s analyze each option to determine why A and C are correct:
Explanation: An InfoSource allows you to break down a complex transformation into smaller, manageable steps. This modular approach simplifies the design and maintenance of data flows. Importantly, the intermediate results are not stored permanently, which optimizes storage usage and improves performance.
For which scenarios do you use the SAP HANA model focus? Note: There are 2 correct answers to this question.
Load snapshots using ABAP CDS Views.
Build views procedures using SQL script.
Define ABAP Managed Database Procedures in data flows.
Define calculations using geospatial functions.
The Answer Is:
B, DExplanation:
TheSAP HANA model focusis a concept that emphasizes leveraging the native capabilities of SAP HANA for data modeling and processing. It is particularly useful when working with advanced features of SAP HANA, such as SQLScript, geospatial functions, and other in-memory database functionalities. The focus is on utilizing SAP HANA's high-performance computing capabilities to perform complex calculations and transformations directly within the database layer.
SAP HANA Model Focus:The SAP HANA model focus is designed to maximize the use of SAP HANA's in-memory processing power. It involves creating models (e.g., calculation views, SQLScript procedures) that are optimized for performance and take full advantage of SAP HANA's advanced features.
SQLScript:SQLScript is a scripting language in SAP HANA that allows developers to write procedural logic and perform complex calculations directly in the database. It is commonly used to build views and procedures that leverage SAP HANA's computational capabilities.
Geospatial Functions:SAP HANA provides robust support for geospatial data and functions. These functions enable you to perform calculations and analyses involving geographical data, such as distances, areas, and spatial relationships.
ABAP CDS Views and AMDPs:While ABAP CDS (Core Data Services) Views and ABAP Managed Database Procedures (AMDPs) are powerful tools for integrating SAP HANA with ABAP applications, they are not directly related to the SAP HANA model focus. These tools are more aligned with ABAP development and are typically used in scenarios where SAP HANA is integrated into an ABAP-based system.
Option A: Load snapshots using ABAP CDS Views.This option is incorrect because loading snapshots using ABAP CDS Views is more aligned with ABAP development rather than the SAP HANA model focus. ABAP CDSViews are primarily used to define reusable data models in ABAP systems, and they do not fully leverage the native capabilities of SAP HANA.
Option B: Build views procedures using SQL script.This option is correct because SQLScript is a core component of the SAP HANA model focus. Using SQLScript, you can create calculation views and procedures that are optimized for performance and take full advantage of SAP HANA's in-memory processing capabilities.
Option C: Define ABAP Managed Database Procedures in data flows.This option is incorrect because ABAP Managed Database Procedures (AMDPs) are part of ABAP development and are used to execute database procedures from within ABAP programs. While AMDPs can interact with SAP HANA, they are not directly related to the SAP HANA model focus.
Option D: Define calculations using geospatial functions.This option is correct because geospatial functions are a key feature of SAP HANA and align with the SAP HANA model focus. These functions allow you to perform advanced calculations involving geographical data, which is a common use case for leveraging SAP HANA's native capabilities.
SAP HANA Developer Guide: The official documentation highlights the use of SQLScript and geospatial functions as key components of the SAP HANA model focus. It emphasizes the importance of leveraging these features to optimize performance and enable advanced analytics.
SAP Note 2700850: This note provides guidance on using SQLScript and geospatial functions in SAP HANA and explains how these features can be integrated into data models.
SAP HANA Academy: Tutorials and training materials from the SAP HANA Academy demonstrate how to use SQLScript and geospatial functions effectively in SAP HANA models.
Key Concepts:Verified Answer Explanation:SAP Documentation and References:Practical Implications:When designing models in SAP HANA, it is important to:
Use SQLScript to create calculation views and procedures that are optimized for performance.
Leverage geospatial functions for scenarios involving geographical data, such as location-based analysis or mapping.
Avoid relying on ABAP-specific tools (e.g., ABAP CDS Views or AMDPs) unless they are explicitly required for integration with ABAP systems.
By focusing on these aspects, you can ensure that your SAP HANA models are efficient, scalable, and aligned with best practices.

Which SAP BW/4HANA objects can be used as sources of a data transfer process (DTP)? Note: There are 2 correct answers to this question.
DataStore Object (advanced)
Open ODS view
InfoSource
CompositeProvider
The Answer Is:
A, CExplanation:
In SAP BW/4HANA, aData Transfer Process (DTP)is used to transfer data between source and target objects. The source objects for a DTP must be compatible with the DTP's functionality, which includes extracting, transforming, and loading data. Below is an explanation of the correct answers:
A. DataStore Object (advanced)ADataStore Object (advanced)is a flexible and powerful object in SAP BW/4HANA that stores detailed data for reporting and analysis. It can serve as a source for a DTP because it supports both inbound and outbound data flows. Data from a DataStore Object (advanced) can be extracted, transformed, and loaded into other objects such as another DataStore Object, InfoCube, or Composite Provider.
What foundation is necessary to use SAP S/4HANA embedded analytics?
SAP HANA optimized business content
ABAP CDS view based virtual data model
Generated external SAP HANA Calculation Views
SAP Agile Data Preparation
The Answer Is:
BExplanation:
SAP S/4HANA Embedded Analytics relies on theABAP CDS (Core Data Services)view-based Virtual Data Model (VDM). This foundation provides a unified layer for data consumption directly from transactional data in the S/4HANA system.
ABAP CDS Views as Foundation:
CDS views define the semantic model for data and integrate seamlessly with SAP S/4HANA.
These views allow users to build advanced reporting and analytics without requiring external data movement.
Virtual Data Model (VDM):
VDM provides a structured framework of CDS views optimized for analytics and reporting.
It includes analytical, transactional, and consumption views tailored for SAP Analytics tools.
