What is the purpose of Child Schedule and Child Schedule Entry in a Maintenance schedule?

We were guided by Service Now developers that an appropriate way of creating a Maintenance Schedule is in the following format:

Maintenance Schedule > Child Schedule > Schedule Entry > Schedule

It was not clear why the following path cannot be used: Maintenance Schedule > Schedule Entry > Schedule

Child schedules can be used to include for example holidays in other schedules. By Creating the child schedule you can reuse that and do not have to add the holidays to each schedule individually.

Child schedule

When a schedule record has one or more child schedules in the Child Schedules related list, schedule entries from the child schedule apply to the containing schedule. By default, there are several sample schedules that use child schedules. For example, see the 8-5 weekdays excluding holidays schedule that includes the U.S. Holidays schedule.

According to me, you create a Schedule first. Then you create a schedule entry, which decides what will be the schedule of the scheduler.

Then you associate an existing schedule as child schedule, such as US holidays, which will also be considered while following working hours schedule.

I dont think you need to follow Maintenance Schedule > Child Schedule > Schedule Entry > Schedule

Hi Svedanth

Please see how maintenance schedule "Servers San Diego" is configured in PDI out of the box (perfect example I have to admit):

1) Maintenance window (aka Schedule) is introduced for server patching, scope of servers described.

2) Schedule entry (aka the exact timing for applying patches) is defined - once per week (on Wedn) from 21OO till 23:00

3) Maintenance team will not work on public holiday, hence it's reasonable to exclude all Wednesdays if they are public holidays (=make a child schedule with holidays).

So, for me: Maintenance Schedule -> Schedule Entry -> Child Schedule

Thank you
