This step returns rows that were previously generated by another transformation in a job. The rows were passed on to this step using the Copy rows to result step. You can enter the meta-data of the fields you're expecting from the previous transformation in a job.
Note: This step produces one or more rows and can not be placed within a stream. It must be the first step in a stream since it produces rows. If you want to add these data to an existing stream, you need to use a join step
