How can I reduce the number of events with the same message generated by workflow SLCs?

If one milestone in a workflow SLC does not start on time, you might not care to be notified that every subsequent milestone is also going to be late starting.

To suppress these subsequent SLC events, use the Fire-Once List parameter when setting up your workflow SLC. To create a fire-once list:
  1. Click the Create button by the Fire-Once List.
  2. Specify a Name and Description, then press Next. The wizard panel is displayed.
  3. Select the message IDs for which you want SLC events to be generated only once per instance of the workflow.
    Note: To get a suggested list of fire-once messages, right-click the messages displayed and choose Suggest Fire-Once list.
