ETL (Extract, Transform, Load) is a critical process in data warehousing, responsible for collecting data from various sources, transforming it into a consistent format, and loading it into the data warehouse for reporting and analysis. In SAP BW/4HANA, ETL processes have evolved to leverage SAP HANA’s in-memory technology and simplified data modeling, making data integration faster, more flexible, and more efficient.
This article provides an overview of the ETL processes in SAP BW/4HANA, covering extraction methods, transformation capabilities, and loading techniques to help data professionals design robust data pipelines.
The extraction phase involves retrieving data from source systems such as SAP ERP, SAP S/4HANA, databases, flat files, and third-party systems.
Transformation involves cleaning, enriching, and converting data into the desired format before loading.
Loading is the final phase where transformed data is stored in SAP BW/4HANA InfoProviders for reporting.
| Feature | Description |
