Explanation:

Maintenance Plans are records that define recurring work orders for preventive maintenance such as inspections or tune-ups[188]. Auto-generate Work Orders is a setting that enables or disables the automatic generation of work orders from maintenance plans[189]. Generation Timeframe is a setting that defines how often work orders should be generated from maintenance plans such as daily, weekly, or monthly[190]. Generation Horizon is a setting that defines how far in advance work orders should be generated from maintenance plans such as 7 days or 30 days[191]. Autogenerating Work Orders with a 14 day Generation Timeframe and a 14 day Generation Horizon would allow Universal Containers to automatically generate Work Orders 14 days before the next suggested maintenance date by creating work orders from maintenance plans every 14 days within 14 days of their scheduled date. Associating a Required Skill called Site Visit to a Maintenance Plan would not affect how far in advance work orders are generated from maintenance plans. Required Skills are fields on the maintenance plan object that indicate which skills are needed for performing preventive maintenance[192]. Associating a Work Type called Site Visit to a Maintenance Plan would not affect how far in advance work orders are generated from maintenance plans. Work Types are records that define the standard tasks and duration for a specific type of work[193].
