Transformation 
The SAP DB Loader provides functions to load, unload, and format
data between different data sources and data targets using different data streams.
The action connected to this is known as a transformation and is described using entries in the SAP DB Loader-specific
system tables.
A transformation is identified using a SAP DB database instance, a transformation type, the desired part of the database catalog, and the data streams.
