Work orders created from preventive maintenance actions are used for more extensive tasks on equipment objects that often require material, special competence, or proper planning; for example: monthly inspection, yearly shutdown, etc. Since a preventive maintenance action is a sort of template, any number of work orders can be generated from it. Upon generation, a quantity of information is copied from the PM action to the work order, e.g., equipment object, action description, maintenance organization that will do the work, resource and material planning, and generation conditions.
In IFS/Preventive and Corrective Maintenance, work orders are automatically created from the PM register when you generate them according to the calendar, event, or criteria. After separate work orders have been generated from PM, you can plan them together with manually registered work orders. Each created work order automatically receives a sequentially ordered, unique ID number, i.e., a work order number. To differentiate PM-generated work orders from manually registered ones, they have two different number series defined at installation time. PM-generated work orders can have any user-defined number series, and if not redefined from the default setting, the PM-generated work orders will be assigned a number from 600,000 and up.
