Definition

All systems that provide BI with data are described as source systems. These can be:

...

       1.      SAP systems

       2.      BI systems

       3.      Flat files for which metadata is maintained manually and transferred to BW using a file interface

       4.      Database management systems into which data is loaded from a database supported by SAP using DB Connect, without using an external extraction program

       5.      Relational or multidimensional sources that are connected to BI using UD Connect

       6.      Web Services that transfer data to BI by means of a push

       7.      Non-SAP systems for which data and metadata is transferred using staging BAPIs.

You define source systems in the Data Warehousing Workbench in the source system tree. To define a source system, choose Create in the context menu of the folder in the source system type.

Integration

DataSources are used to extract and stage data from source systems. The DataSources subdivide the data that is provided by a source system into self-contained business areas.

The following graphic provides an overview of the data transfer sources supported by BI and shows the interfaces that you can use:
