Parent and child schedules

concept brazil Updated Sep 10, 2026 2 min read c_ParentAndChildSchedules.md

Schedules can have one of two parent-child relationships with other schedules.

Parent field

When a schedule record lists a value for the Parent field, schedule entries from the parent schedule apply to both the parent schedule and the child schedule. By default, there are no sample schedules that use the Parent field.
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.

Parent and child schedules cannot contain conflicting schedule entry types. For example, a schedule containing maintenance schedule entries cannot also contain blackout schedule entries. Nor can a maintenance schedule have a child schedule containing blackout schedule entries.

Note: To create a Holiday schedule and include it in a parent schedule, you must add it as a child schedule and with an Include type.

Parent schedules must have at least one entry that is not an Excluded type. If parent schedules are only exclusionary, they are invalid.

Note: The Show Schedule related link shows schedule entries from the current schedule and the child schedule record. For example, when showing the 8-5 weekdays excluding holidays schedule, holidays are also shown as excluded because the holiday schedule is a child schedule.

# Parent and child schedules

Schedules can have one of two parent-child relationships with other schedules.

-   **Parent field**

    When a schedule record lists a value for the **Parent** field, schedule entries from the parent schedule apply to both the parent schedule and the child schedule. By default, there are no sample schedules that use the **Parent** field.

-   **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.


Parent and child schedules cannot contain conflicting schedule entry types. For example, a schedule containing maintenance schedule entries cannot also contain blackout schedule entries. Nor can a maintenance schedule have a child schedule containing blackout schedule entries.

**Note:** To create a Holiday schedule and include it in a parent schedule, you must add it as a child schedule and with an Include type.

Parent schedules must have at least one entry that is not an **Excluded** type. If parent schedules are only exclusionary, they are invalid.

**Note:** The **Show Schedule** related link shows schedule entries from the current schedule and the child schedule record. For example, when showing the **8-5 weekdays excluding holidays** schedule, holidays are also shown as excluded because the holiday schedule is a child schedule.
