The Master PM application serves as a template to manage common information for a group of associated Preventive Maintenance (PM) records. Key information managed includes the job plan, asset details, and scheduling frequency. When scheduling information, such as the frequency, is updated on the Master PM and then applied to the associated PMs, it directly changes the calculated due dates for future work. The PM Forecast is a projection of these future due dates. Therefore, updating the Master PM's scheduling data effectively updates the forecast for all linked PMs.

A. Work Order Status: Work Order Status is managed in the Work Order Tracking application after a work order is generated from a PM; it is not updated from the Master PM.

C. Generate Work Orders: This is an action performed on individual PM records to create work orders. It is not a data field that is updated within the Master PM template itself.

D. PM Hierarchy: A PM hierarchy, which defines parent-child relationships between PMs, is configured directly in the Preventive Maintenance application, not through the Master PM application.

1. IBM Maximo Manage 8.0 Documentation, "Master PMs": "A master PM is a template that is used to create preventive maintenance (PM) records. You can use a master PM to specify job plan, frequency, and asset information for a group of PMs... When you change information on the master PM, you can choose to apply the changes to the associated PMs." This confirms that frequency, a key driver of the forecast, is managed here.

2. IBM Maximo Manage 8.0 Documentation, "Forecasting PMs": "You can generate a forecast for a preventive maintenance (PM) record to see the dates on which work orders are due to be generated. The forecast is based on the frequency information in the PM record and on the work order generation criteria." This directly links the forecast to the frequency information managed by the Master PM.
