# Priorities

In **PADS4 Scheduler**, every scheduled presentation is assigned a **priority**. This priority determines which presentation is displayed in cases where multiple schedules overlap in time for the same destination.

By default, priority levels include **High**, **Medium**, and **Low**, but custom levels can be defined and modified using the **PADS4 System Management** application.

> Access to specific priority levels can also be controlled through **user permissions**.

***

## Priority

* When multiple presentations are scheduled for the **same time period**, the one with the **highest priority** will be shown.
* Priority is a **required field** when creating a schedule.
* You can **modify the priority** of a scheduled presentation at any time after creation.

> For example: If a **High priority** presentation overlaps with a **Medium priority** presentation, only the **High priority** content will be displayed.

***

## Sub Priority

If multiple scheduled presentations have the **same priority level** and **overlap in time**, PADS4 uses an internal system called **sub priority** to decide which presentation is shown.

### How Sub Priority Works:

* The **sub priority** is automatically set based on the **creation time** of the schedule.
* The presentation scheduled **most recently** will have the **highest sub priority** and will be displayed.
* **Sub priority is not updated** when editing the presentation or schedule. It only reflects the original creation timestamp.

***

## Adjusting Sub Priority

Although sub priority is not directly visible, you can **manually adjust it** using the Scheduler interface.

To change a presentation's importance:

1. Go to the **Home** tab in the Scheduler’s ribbon bar.
2. In the **Priority** group, use:
   * **Increase Priority**: Raises sub priority, giving it preference over others with the same main priority.
   * **Decrease Priority**: Lowers sub priority, reducing its chance to override similar-priority presentations.

This allows finer control in scheduling conflicts without changing the main priority level.
