With this transformation it is possible to compose a job that embeds functionality from another saved job.
The job that is invoked will be stripped from it's analysis section, which means that only transformations remain. That way you can split up complex transformation flows into smaller pieces - each represented as a job file.
To configure the transformation, select the columns from your current job's source which needs to be piped into the child job. The amount of columns selected needs to be the same as the amount of columns defined in the child job. This will be checked automatically, making it impossible to run the transformation otherwise.
