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.

The maintenance group rule used to generate the work orders: All maintenance groups or Selected maintenance groups. Select the appropriate option. If you choose Selected maintenance groups, APM only reviews the standard jobs for the maintenance groups you choose.

The work type rule used to generate the work orders: All work types or Selected work types. Select the appropriate option.
