SAP BW sources in mappings

To read data from SAP BW, configure an SAP BW object as a source in a mapping.
Specify the name and description of the SAP BW source. Configure the source and advanced properties for the source object.
You can parameterize the SAP BW source connection at run time with values specified in a parameter file.
The following table describes the SAP BW source properties that you can configure in a Source transformation:
Property
Description

You can select an existing connection, create a new connection, or define parameter values for the source connection property.
To overwrite the source connection properties at run time, select the Allow parameter to be overridden at run time option.
Source Type
Type of the source object.
Select one of the following source types:
  • - Single Object. Select to specify a single SAP BW object.
  • - Parameter. Select to specify a parameter where you define values that you want to update without having to edit the mapping.
