Get rows from result
PLEASE NOTE: This documentation applies to an earlier version. For the most recent documentation, visit the Pentaho Enterprise Edition documentation site.
Description
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
