In the PM application, there is an 'Alert Lead Days' field which can be used to Alert users when a work order is due ahead of time.
Alert is when you create a WO from methods other than PM for same asset, it will alert you by a warning message that a PM is due for this Asset.
In order to enable this option, we need a system admin level setting in Organizations application -> Select Action -> PM Options.
