A trigger is a text string that the IBM® EMM Scheduler can send when a run completes successfully or when a run fails. If you have a schedule that sends a trigger on completion, you can set another schedule to start a run when it receives that trigger.
You can schedule a set of Campaign flowcharts to run at the same time by giving all of them the same trigger. You can also use triggers to cause a set of flowcharts to run in series, one after another.
