# Notification

:lock: Notification.**Show**

## Overview

A **Notification** represents an asynchronous alarm. A **Notification** has a user defined severity and it can target a specific Employee, Role or Everyone. It is also possible to configure the type of tracking and clearance, which can be of three types:

1. **ManualSingleUser** - the first **Employee** that clears the Alarm will close the Alarm.
2. **ManualEveryUser** - every **Employee** must clear the Alarm. In this case, a *Valid To* date must be set.
3. **Automatic** - the system will clear the Alarm automatically once the *Valid To* date is reached.

Furthermore, it is possible to filter the visibility of each **Notification** to a particular **Facility**, **Area**, **Resource** or **Steps**. Filtering in the GUI is performed against the current user employee **Workgroup**.

**Notifications** are sent to the GUI using a publish/subscribe mechanism. The GUI will display the number of notifications in a notification icon in the status bar. The different severities, colors and display behaviors are configured in the generic table *NotificationSeverity*.

!!! info
	Notifications are part of notifications, which is a Critical Manufacturing optional module.

!!! info
	The user must have an **Employee** object associated to be able to view/receive **Notifications**, but this is not necessary if the user wants to create a **Notification**.

## Sequence Of Steps

The necessary steps for correctly configuring and using a **Notification** are the following:

1. Create the different notification types and severities in the lookup tables *NotificationType* and *NotificationSeverity*.
2. Configure the different severities in the generic table *NotificationSeverity*.
3. Create the **Notification**.
