All assets in the site: This option enables you to generate work orders for assets throughout the plant; for example, you could generate all work orders to be completed during the plant’s summer shutdown.
This asset and its descendants: This option enables you to generate only the work orders required for a selected asset and its child assets. When you select this option, you must also select a specific asset.

Generate work orders based on the jobs’ due dates: Enter the number of days in the future that you want work orders to be generated. When you run PM generation using this profile, the system calculates the horizon date by adding this number of days to the current date. Work orders that need to be started by the calculated horizon date are generated.
Generate work orders for a shutdown: Select the shutdown type and the number of days in the future for the planned start of the shutdown. Work orders that need to be performed during the shutdown will have their planned start dates set to this date.

To have the PM generation profile executed by the Action Scheduler, select Automatically based on a recurrence pattern. You can then set up the recurrence pattern.
