SAP BW Transformation
The transformation is the program which maps one InfoProvider to another. It is the core of the ETL in BW, as all data transformations are defined here. InfoObjects are mapped here, and transformation rules can be defined, if necessary with ABAP programming. In order to launch a transformation, so that the data is transformed and loaded from one InfoProvider to another, a Data Transfer Process (DTP) needs to be launched which is linked to the transformation.
