# Assign Materials To Production Order

:lock: ProductionOrder.**Assign**

## Overview

This operation is used to assign one or more **Materials** to a **Production Order**.

## Setup

No special setup is required other than to meet the preconditions of the transaction.

## Preconditions

* The old **Materials** (if any) and new **Production Orders** are active and in the state Created, Released, In Progress or Completed.
* The old **Materials** (if any) and new **Production Orders** must not be restricted.
* The **Materials** to be re-assigned must be active.
* If the **Production Order** has the option Validate Material Products set to `true`, the **Materials** to be assigned must have a **Product** which belongs to the reverse **Product** tree of the **Production Order** **Product**.

## Sequence of Steps

1. Optionally, review the **Production Order** details by expanding the **Production Order** section.
2. Add as many **Materials** as desired to the grid.
3. Select **Assign** to complete the operation.

This wizard provides the following additional options:

* Apply Production Order priority to Materials - whether to set the **Material** priority with the **Production Order** priority.
* Apply Production Order planned end date to **Materials** - whether to set the **Material** due date with the **Production Order** due date.
* Account to old Production Order - whether the **Material** should still account for the old **Production Order**.
* Account to new Production Order - whether the **Material** should account for the new **Production Order**.
* Apply changes recursively to Sub-Materials - whether the changes apply recursively to all **Sub-Materials** that have the same type as the parent **Material**.
* Remove from old Production Order - whether the **Material** will be removed from the old **Production Order**.

!!! info
    It is possible to define the default value for Apply change recursively for all Sub-Materials by editing the entry Context = `ProductionOrder.AssignMaterials` and Element = `ApplyToAllSubMaterials` in the [[guielementdefaultvalue-gt]] Generic Table.
