# Special Update Maintenance Activity Order Schedule/Counters

:lock: MaintenanceActivityOrder.**SpecialUpdateScheduleAndCounters**

## Overview

This operation updates the schedule and counters of a **Maintenance Activity Order** (**MAO**). This transaction is similar to the [[user-guide-update-schedule-counters|Update Maintenance Activity Order Schedule and Counters]] except that the current user is not required to belong to the **Maintenance Plan Instance** Owner Role of the **MAO**.

## Preconditions

* The **MAO** is in the execution state Requested, Approved, or Released.
* The **MAO** is not Ad hoc.
* If the **MAO** is included in another **MAO**, that is, the Parent **MAO** property is not `null`, this operation can only be performed if the Schedule Type of the **MAO** is set to Usage Based or Time And Usage Based. In this case, the only property that can be modified is the Usage Counter value.

## Sequence of Steps

### Step 1

1. Verify the information regarding the **MAOs**.

    !!! note
        It is possible to select multiple MAOs before entering the Special Rework Maintenance Activity Order wizard.

2. For Time Based and Time And Usage Based **MAOs**, set the Time Early Due, Time Due and Time Late Due.

    !!! note
        Ensure that Time Early Due is set to a value earlier than Time Due, and Time Due is earlier than Time Late Due.

3. For Usage Based and Time And Usage Based **MAOs**, set the Usage Early Due, Usage Due and Usage Late Due.

    !!! note
        Ensure that Usage Early Due is set to a value lower than Usage Due, and Usage Due is lower than Usage Late Due.

4. For Time Based and Time And Usage Based **MAOs**, it is possible to set the Schedule Date.
5. Optionally, enter a Comment.
6. Select **Update** to complete the operation.
