Interview Questions and Answers

A CompositeProvider is a data model object that allows you to combine data from multiple InfoProviders (e.g., ADSOs, InfoObjects) using union or join operations. This allows for flexible data modeling and reporting across different data sources.

An Advanced DSO is a flexible and optimized data storage object in SAP BW/4HANA that can be configured to support various use cases, including standard reporting, staging, and direct updates. It replaces the older DSO types.

SAP BW is a traditional data warehousing solution that can run on various databases. SAP BW/4HANA is the next generation data warehouse that is specifically optimized to run on the SAP HANA in-memory platform. BW/4HANA offers simplified data modeling, improved performance, and new functionalities like native HANA integration.

Standard DSO is used for standard reporting and typically has three tables. Write-optimized DSO is used for fast data loading, often from staging areas, and has a single table. Direct Update DSO allows direct data writes from external applications and is often used for planning scenarios.

A Process Chain is used to automate and schedule a sequence of data loading and processing steps in SAP BW/BI. This includes extraction, transformation, loading, and index creation.

Master Data refers to descriptive information about key business entities, such as customers, materials, or employees. It provides context and meaning to transactional data. Examples of Master Data include attributes, texts, and hierarchies.

Different types of Master Data include Attributes (descriptive properties), Texts (descriptions in different languages), and Hierarchies (organizational structures).

Objects in SAP BW/BI are transported using the Change and Transport System (CTS). Transport requests are created to group related changes and move them between different SAP systems (e.g., development, testing, production).

BEx Analyzer is a Microsoft Excel-based reporting tool within SAP BW/BI. It allows users to analyze data from InfoCubes and DSOs using pivot tables, charts, and other visualization techniques.

SAP Analytics Cloud (SAC) is SAPs cloud-based analytics solution. It offers capabilities for business intelligence (BI), planning, and predictive analytics, and it integrates with SAP BW/BI.

Query performance can be optimized by: Using aggregates, optimizing InfoCube design, using appropriate partitioning, minimizing the amount of data retrieved, and properly indexing tables.

Aggregates are pre-calculated summaries of data in InfoCubes. They improve query performance by reducing the amount of data that needs to be processed at runtime. However, they require additional storage space and maintenance.

An InfoPackage is a control object used to schedule and manage the extraction of data from source systems into SAP BW/BI. It defines the selection criteria, data source, and other parameters for the extraction process.

Business Content is pre-defined data models, reports, and queries provided by SAP. Its designed to accelerate the implementation of SAP BW/BI by providing a starting point for common business scenarios.

Transformations are used to convert and cleanse data from the source system into a format suitable for loading into the target data storage objects (InfoCubes, DSOs). They involve tasks like data type conversions, calculations, and filtering.

A DataStore Object (DSO) is a storage area in SAP BW/BI that holds granular, transactional data. Its used for detailed reporting and analysis, often serving as an intermediate storage layer for data before its loaded into InfoCubes.

InfoCubes are designed for analytical reporting, optimized for fast aggregation. DSOs are designed for detailed reporting at the transaction level and offer overwrite functionality. DSOs have key fields, and InfoCubes use dimensions.

The key components include: Data Sources, Extraction, Transformation, and Loading (ETL) processes, Data Storage (InfoCubes, DataStore Objects (DSOs), Advanced DSOs), Reporting and Analysis tools (BEx Analyzer, Web Application Designer, SAP Analytics Cloud).

An InfoCube is a multidimensional data storage object in SAP BW/BI used for analytical purposes. It consists of fact tables containing key figures and dimension tables containing characteristics.

SAP BW/BI (Business Warehouse/Business Intelligence) is a data warehousing and reporting solution from SAP. Its used for collecting, storing, analyzing, and presenting data from various sources (both SAP and non-SAP) to enable informed decision-making.
