Manual versus Automatic Steps
MDM workflow supports two kinds of steps:
· Manual
A manual step appears in the cascading Next Step menus and requires user action before the task is manually sent to the next user in the step or the next step in the workflow.
· Automatic
An automatic step does not appear in the cascading Next Step menus and does not require user action; MDM performs the task and automatically sends the workflow to the next step.

Automatic steps include Assign, Notify, Validate, and Syndicate, and Merge and Connect (which are not functional).
Even though they are invisible, automatic steps (such as a Validatestep) may generate errors that prevent the job from moving to the selected next step.
