An extended date overrides a preventive maintenance (PM) record's typical next due date for generating PM work orders. This date only applies to the current PM record; it does not apply to other PMs in a PM hierarchy.
The Extended Date and related fields are on the Frequency tab in the Preventive Maintenance and Master PM applications.
Things to know about extended dates:
If the Adjust Next Due Date check box is selected, the calculation of the next due date after a work order is generated from the PM is: Extended Date + Frequency.
If the Adjust Next Due Date check box is cleared, the calculation is: Next Due Date + Frequency.
If the extended date is later than the calculation of the Next Due Date + Frequency, you can disrupt the frequency cycle of the PM. A warning window advises you that using such an extended date can disrupt the frequency cycle and job plan sequence of the PM.
