Nesting schedules

Schedule Manager allows you to insert an existing published schedule into another schedule. This concept is termed nesting schedules.

The schedule containing an inserted schedule is termed a master schedule; the inserted schedule is termed a subschedule.

A normal schedule is a schedule that is neither a master schedule nor subschedule.

The following rules apply to master schedules, subschedules, and normal schedules:

• You cannot insert a schedule under a subschedule.
• If you remove all subschedules from a master schedule, the master schedule becomes a normal schedule.
• If you remove a subschedule from a master schedule, and if the subschedule is not part of any other master schedules, it becomes a normal schedule.
• A schedule can become a subschedule only if its start and finish dates are within the start and finish dates of the schedule in which it is to be inserted.
• A schedule can become a subschedule in more than one master schedule.
• A subschedule can be a master schedule in another schedule.
• Changing a property in a subschedule is global; that is, the property is changed in every instance that the subschedule is used.
• You can insert a master schedule into another master schedule and the original master schedule becomes a subschedule. All subschedules in the original master schedule are included. Consequently, you can create multiple levels of subschedules.

Nesting patterns

• Single-layer nesting — schedule New Master is a master schedule and contains subschedules New Sub-Sch-A and New Sub-Sch-B.
• Double-layer nesting — schedule New Master is inserted into schedule Sub-sched-A. In this instance, Sub-sched-A is considered a master schedule. Schedule New Master becomes a subschedule and schedules New Sub-Sch-A and New Sub-Sch-B are included under schedule New Master.
• Complex-layer nesting — schedule Sub-sched-A is inserted in schedule Master. Schedule Sub-sched-A is now a subschedule in schedule Master. Schedule New Master is included, illustrating the complexity of nesting schedules.
