Oracle Enterprise Asset Management enables you to generate work orders automatically based on meter readings, runtime intervals, and calendar days. Preventive maintenance activities reduce the probability of failure or degradation of the assets' physical conditions. These activities are executed periodically, by usage, or based on the condition of an asset number (asset or rebuildable serial number). Meters are entered to measure any asset number that needs to be measured and periodically serviced, based on the measurement. For example, a pipe may start out at 12 millimeters, but when it wears to only four millimeters, it needs to be replaced (See: Meters).

Scheduling definitions are defined to create forecasted, scheduled work orders, based on meter readings. You can create a Preventive Maintenance scheduling definition (See: Preventive Maintenance Scheduling) for an asset number or rebuildable item and activity combination (See: Associating Asset Numbers with Activities), or an asset route (See: Defining Asset Routes). After you have defined Preventive Maintenance scheduling definitions, the Preventive Maintenance scheduler process may execute. You can view these forecasted work orders using the Maintenance Workbench (See: Using the Maintenance Workbench). You can execute the Generate Preventive Maintenance Work Orders process. When this process executes, work orders are created with a status of Unreleased. (See: Generating Work Orders). You can choose the Implement button to change the status of the Unreleased work orders to Released work orders.
