Enable runtime column propagation for parallel jobs

Before you can enable runtime column propagation in a stage, runtime column propagation must be enabled for parallel jobs at the project level from the IBM InfoSphere DataStage and QualityStage Administrator. If you enable this feature, stages in parallel jobs can handle undefined columns that they encounter when the job is run, and propagate these columns through to the rest of the job.

About this task

This check box enables the feature, to actually use it you need to explicitly select the option on each stage. Enabling this feature makes the following sub-property available:

Enable Runtime Column Propagation for new links. Select this to have runtime column propagation enabled by default when you add a new link in a InfoSphere® DataStage® job. If you do not select this, you will need to enable it for individual links in the stage editor when you are designing the job.
