SAP Online Documentation: Data Acquisition


SAP BW∕4HANA offers flexible ways of integrating data from various sources. 

The sources are connected with the SAP BW∕4HANA using source systems. SAP BW∕4HANA provides interfaces for extracting and transferring data from a large number of sources. To transfer the data, you need a DataSource in SAP BW∕4HANA. The data is loaded in SAP BW∕4HANA using the data transfer process, with transformation and filters. Transformations are used in the data transformation process in order to consolidate, clean and integrate the data.
