# Begin Maintenance Activity Order

:lock: MaintenanceActivityOrder.**Begin**

## Overview

This operation initiates the execution of a **Maintenance Activity Order** (**MAO**) which has been Released.

## Preconditions

* The **MAO** is in the Released execution state.
* If a **MAO** has an assigned Owner Employee, the current user must either be assigned as the **MAO** Owner or belong to the designated Owner Role, depending on how ownership is configured for the specific **MAO**.
* The **MAO** must not be included in another **MAO**, that is, the Parent **MAO** property must be `null`.
* There must be an **Employee** associated to the user.

## Sequence Of Steps

### Step 1

1. Verify the information regarding the **MAO**.
2. If a state transition is associated with the entity to which the **MAO** is related, it is possible to change the state of the entity by selecting a new state from the list. If the state transition has **Reasons** associated, you can accept the suggested **Reason** or select another one.
3. Optionally, enter a Comment.
4. Select **Begin** to complete the transaction.

!!! note
    A Maintenance Activity Order can have the Product Part Type set to Repairable only if maintenance is performed on a Resource that has the Defines Resource Parts property enabled, and the specified Product and Designator match an existing Resource Part.

    If the Maintenance Type of the MAO is set to Qualification and the Type Restriction Mode is set to Require None, all associated Qualification Checks whose state is not `Obsolete` change state to `In Progress` when the MAO begins.

    If the Auto-Begin Qualification property was enabled when setting up the Maintenance Activity, the system automatically begins the Maintenance Activity Order. For more information, see [[user-guide-create-maintenance-plan#step-3-adding-maintenance-activities|Adding Maintenance Activities]].
