Horizon Date: Work orders will be created from time-based standard jobs that are due between now and the date you enter. If more than one work order should be created from a standard job in that time period, the appropriate number of jobs will be created. For example, if a standard job is triggered every week and you enter a horizon date four weeks from now, four work orders based on that standard job will be created.
Shutdown: Work orders will be created for standard jobs that are triggered by the planned shutdown you select. In addition, work orders will be created for time-based standard jobs that come due on or before the shutdown date entered.
