# Manage Qualification Materials

:lock: MaintenanceActivityOrder.**AssignMaterialsToQualification**

:lock: MaintenanceActivityOrder.**ManageQualificationMaterials**

## Overview

This operation is used to manage Qualification Materials in a **Maintenance Activity Order** (**MAO**). If you want to assign or unassign **Materials** to each individual **MAO Qualification Check**, use the [[user-guide-special-manage-qualification-materials]] operation.

## Preconditions

* The **MAO** exists and is Active.
* The **MAO** Maintenance Type is set to Qualification.
* The **MAO** Material Type Restriction Mode is set to Require Specific.
* The **MAO** Execution State is Requested, Approved, Released, In Progress, or Waiting For Acceptance.
* There must be at least one **MAO** **Qualification Check** whose system state is neither Completed or Obsolete.
* If assigning the **Material** sets the corresponding **MAO Qualification Check** to `In Progress`, the additional conditions required for that transition must be satisfied.
* The **Material** exists, is Active, and Non-Template.
* The **Material** is Top-Most and not in an Off-Flow (either Temporary Off-Flow or Rework).
* The **Material** Pick List Item Count must be empty.
* The **Material** In Transfer Order Item must be empty.
* If the **Material** is associated with a **Resource**, and the state of the **Material** is Consumable, Durable, Dispatched, In Process, or the property In Store is set to `true`, the **Resource** Inventory Locked must be `false`.
* The **Material** Is Approved property must not be set to `false`.
* The **Material** Expiration Date is `null`, or if defined, it must be in the future.
* The Source Material Floor Life must be valid. This condition is met if any of the following applies:
    * Floor Life Remaining Hours is `null`; or
    * Floor Life Remaining Hours is greater than `0` and the Floor Life Counter State is Stopped; or
    * The Floor Life Counter State is Running, and the Floor Life Remaining Hours - calculated as `Floor Life Remaining Hours - (Now() - Floor Life Open Date)` - is greater than `0`.
* The **Material Product** must not be blocked or if blocked, the **Material** property Override Product Block must be `true`.
* The **Material** is in the same **Facility** of the **MAO** object (**Resource** or **Area**).
* The **Material** is Queued or Dispatched.
* The **MAO** Material Type matches the Type of the **Material**.
* If the **MAO** **Product** is set, it must match the **Product** of the Top-Most **Material**.
* If the **MAO** Flow Path is set, it must match the **Flow Path** of the Top-Most **Material**.
* If the **MAO** Logical Flow Path is set, it must match the **Logical Flow Path** of the Top-Most **Material**.
* The **MAO** **Step** must match the **Step** of the Top-Most **Material**.
* If a Minimum Quantity is set in the **MAO**, the Material Primary or Secondary Units must match the Minimum Quantity Units defined.
    * If the Minimum Quantity Units matches the Material Primary Units - the Material Quantity (Primary Quantity + Sub-Materials Primary Quantity) is greater or equal to the Minimum Quantity value defined.
    * If the Minimum Quantity Units matches the Material Secondary Units - the Material Quantity (Secondary Quantity + Sub-Materials Secondary Quantity) is greater or equal to the Minimum Quantity value defined.

## Sequence of Steps

1. Select a **MAO** that matches the preconditions above.
2. On the top ribbon, select the **Manage** dropdown, then choose **Manage Materials**. Alternatively, go to the **Materials** section, open the **Manage** dropdown, and select **Manage Materials**.
3. In the **Manage Qualification Materials** wizard, assign or unassign the required **Materials** using the :material-plus: and :material-trash-can: icons. When a **Material** is selected, its details are displayed in the panel below. If no **Materials** are available for selection, review the preconditions described above.

    !!! info
        If assigning a Material sets the corresponding MAO Qualification Check to `In Progress`, the system also sets the Material-Resource Running Qualification.

4. Optionally, enter a comment.
5. Select **Update** to complete the operation.
