Title: Data Extraction from Non-SAP Sources into SAP BW/4HANA
Subject: SAP-BW/4HANA in SAP Field
SAP BW/4HANA is a powerful data warehousing solution designed for integrating, modeling, and analyzing large volumes of data from diverse sources. While SAP BW/4HANA naturally integrates well with SAP systems, many enterprises require extracting data from non-SAP sources to get a comprehensive view of business information.
This article discusses the methods, tools, and best practices for extracting data from non-SAP sources into SAP BW/4HANA, enabling seamless integration and effective reporting.
- Enterprises often use heterogeneous IT landscapes comprising legacy systems, third-party applications, cloud platforms, and databases outside the SAP ecosystem.
- To enable end-to-end analytics, data from these non-SAP sources must be brought into BW/4HANA.
- Examples of non-SAP sources include Oracle, SQL Server, Salesforce, flat files (CSV, XML), web services, and IoT platforms.
SAP BW/4HANA supports various extraction methods tailored for different non-SAP data sources:
- A powerful ETL tool that extracts, transforms, and loads data from multiple non-SAP sources.
- Supports connectors for databases, flat files, web services, and big data.
- Enables complex transformation logic and data quality checks before loading into BW/4HANA.
- Data Services jobs can be scheduled and monitored within the SAP environment.
- Open ODS Views allow virtual access to external database tables or views without physically loading data.
- Supports connections to databases like Oracle, SQL Server, and HANA via remote source adapters.
- Enables real-time or near real-time reporting on non-SAP data alongside BW data.
- Useful for scenarios requiring minimal data replication.
¶ 3. Flat File and FTP Data Loads
- BW/4HANA supports loading data from flat files such as CSV, XML, or Excel.
- Files can be imported via SAP GUI or automated through process chains.
- Useful for batch processing data received from external systems not connected directly.
¶ 4. OData and Web Services Integration
- BW/4HANA can consume data from web services exposing data via OData or SOAP protocols.
- Facilitates integration with cloud applications and SaaS platforms.
- Requires setting up HTTP connections and service consumers in the BW system.
- Middleware like SAP CPI, Dell Boomi, or MuleSoft can extract, transform, and route data from non-SAP sources into BW/4HANA.
- Provides scalable and robust integration for complex landscapes.
-
Identify Data Source and Connectivity
Understand the data format, volume, update frequency, and available connection options.
-
Choose the Extraction Method
Decide between physical data load (ETL), virtual access (Open ODS Views), or real-time integration (web services).
-
Configure Source System Connection
Set up database connections, file transfer protocols, or service endpoints in BW/4HANA.
-
Design Data Models
Create DataStore Objects, Open ODS Views, or CompositeProviders as needed for storing or modeling the incoming data.
-
Implement Data Extraction Logic
Use ETL tools or direct extraction methods to map, transform, and load data into BW.
-
Schedule and Monitor Loads
Use process chains, Data Transfer Processes (DTPs), or middleware schedulers for automation and error handling.
- Data Profiling: Analyze source data for quality, consistency, and volume before extraction.
- Minimize Data Duplication: Use virtual providers where possible to reduce data storage.
- Optimize Data Loads: Use delta mechanisms for incremental loading to improve efficiency.
- Secure Connections: Ensure secure communication channels with encryption and authentication.
- Error Handling: Implement robust error monitoring and recovery processes.
- Documentation: Maintain clear documentation of data flows and transformation rules.
Extracting data from non-SAP sources into SAP BW/4HANA is essential for comprehensive enterprise analytics. SAP BW/4HANA offers versatile and flexible options, including ETL with Data Services, virtual access via Open ODS Views, file-based loading, and web services integration.
Choosing the right approach based on data characteristics and business needs ensures seamless integration, enabling organizations to harness full data potential for informed decision-making.
