Answer / ramjanaki

I think you are referring to the Mapping of Columns in the
Transformer Stage.

It is nothing but relating the columns from the source
stage to the target in the Transformer stage by drag and
drop. Transformations like for example, doing some
condition check, applying some functions etc., can be done
here and the resultant data will be loaded to the target.
