Nesting schedule templates
Schedule nesting also applies to schedule templates. The following list details the functionality of Schedule Manager as it applies to schedule templates:
Creating a master schedule from a master schedule template This process is similar to creating a schedule from a single template. When you create a master schedule from a master schedule template, the created schedule is a normal schedule, not a master schedule. In addition, Schedule Manager creates a list of tasks from the various subschedule templates. After the new master schedule is created, it has no reference to the subschedule templates and master schedule template.
Inserting a schedule template into a master schedule template This process is similar to inserting schedules into a master schedule. During the process, only schedule templates are displayed in the dialog box and can be inserted. Non-template schedules are not shown.
Master schedule template membership When a schedule template is inserted into a master schedule template, the membership of the master schedule template is added to the subschedule template membership. Master schedule members are automatically given read access to subschedules in context of the master schedule. Master schedule template members do not automatically get write access to the subschedule template.
Updating a subschedule template When a task within a subschedule template is updated such that it causes its roll up task to be updated, the recalculate flag is set indicating a change has occurred. The next time the master schedule template is opened, Schedule Manager recalculates schedule values.
Changing the template flag The template flag in the schedule properties cannot be changed after a schedule template is part of a master schedule template. In addition, the template flag in the master schedule template cannot be changed if there are subschedule templates. To unset the template flag on the master schedule template, you must remove all subschedule templates from the master template.
