# Maintenance Activity Order

:lock: MaintenanceActivityOrder.**Show**

## Overview

**Maintenance Activity Orders** (**MAOs**) are accessed via a Scheduler available in the [[user-guide-maintenance-index|Maintenance Group]], either in the [[user-guide-execution]] or the [[user-guide-management]] view, according to the Role that the user currently holds. The time and usage based **MAOs** are always created automatically by the system. Ad hoc **MAOs** are created via a manual request using the [[user-guide-request-maintenance-activity-order]] function.

A **Maintenance Activity Order** can be of four types:

* **Time** based - the trigger is activated by time.
* **Usage** based - the trigger is activated by usage.
* **Time** and **usage** based - the trigger is activated either by time or usage.
* **Ad hoc** - the trigger is activated manually.

Besides the Universal state, the **MAO** has two important independent system states:

* **Schedule State** - defines the **MAO** state from a scheduling (triggering) perspective. Possible values are:
    * Before early due
    * Early due
    * Due
    * Late due

* **Execution State** - defines the **MAO** from an execution perspective:
    * Requested
    * Approved
    * Released
    * In Progress
    * Waiting For Acceptance
    * Closed
    * Rejected
    * Reworked
    * Skipped
    * Closed As Joined
    * Canceled

When viewed within the context of a schedule, the vertical line on the left of a **Maintenance Activity** represents the Schedule State as described in the next picture.

```

The background color of a **Maintenance Activity** represents whether the **Maintenance Activity** is In Progress (in green) or Released (in light blue).

On the right side of the **Maintenance Activity**, two icons indicate the Type and the Execution State:

The execution workflow is described in the next picture.
