Examples: Linking PM Schedules Using the Days Tolerance Method

When the Preventive Maintenance or Projection process schedules maintenance, and you defined secondary schedules with the days tolerance method, the system compares the calculated due date of the primary schedule due date to due date of each linked secondary schedule and:

  • Links the scheduled maintenances if the dates are the same.

  • Links the scheduled maintenances if the difference between the dates is less than or equal to the days tolerance defined on the linked secondary schedule.

    Note:

    The due date of the primary schedule can be a number of days earlier or later than the due date of the secondary schedule as long as the number of days is within the specified days tolerance.

  • Does not link the maintenances if neither of these scenarios occur.

  • Example 1

  • Major service due date: 05/22/2009

  • Minor service due date: 05/25/2009

  • Current date: 05/22/2009

  • Days tolerance: 7 days

  • Maintenances will be linked.

  • Example 2

  • Major service due date: 05/22/2009

  • Minor service due date: 05/31/2009

  • Current date: 05/22/2009

  • Days tolerance: 7 days

  • Maintenances will NOT be linked.

  • Example 3

  • Major service due date: 05/26/2009

  • Minor service due date: 05/22/2009

  • Current date: 05/22/2009

  • Days tolerance: 7 days

  • Maintenances will be linked.

  • Example 4

  • Major service due date: 05/22/2009

  • Minor service due date: 05/22/2009

  • Current date: 05/22/2009

  • Days tolerance: 7 days

  • Maintenances will be linked.
