# Start Production Order

:lock: ProductionOrder.**Start**

## Overview

This operation starts a **Production Order** by creating as many **Materials** as required, according to the minimum and maximum **Material** size defined for the **Production Order** **Product** and the **Production Order** Quantity. The operation will also compute the **BOM** requirements and will create as many **Materials** as required for each **BOM** item, provided that the property Include In Scheduling for those **Products** is set to `true`. The **BOM** Explosion is performed recursively. The **Production Order** will be set to the state Released after this transaction is executed.

!!! note
    If there is a BOM of scope Materials associated to a Material that has characteristics, the system will only display BOM Products that have the same characteristics defined for the selected Material.

## Setup

A Default Type and Default Form must both be defined for the **Product** of the **Production Order** to be started, as well as for any sub-component **Products**. It is also possible to specify the maximum material per **Product** and to define **BOMs** for the **Product** along the **Flow**.

!!! info
    When Order Management is used, Due Dates are set at the Material level. If you do not want this behavior, you can use the following configuration `/Cmf/System/Configuration/OrderManagement/ProductionOrderStart/IgnoreMaterialDueDate` (defaults to `false`).

## Preconditions

* The **Production Order** must be active and in the state Created.
* The **Production Order** must have the property Include in Planning set to `true`.

## Sequence of Steps

1. Optionally, review the **Production Order** details by expanding the **Production Order** section.
2. Choose whether to activate the **BOM** explosion, recursively starting also **Materials** for the sub-components according to the **BOMs** defined for the **Production Order** **Product** standard **Flow**.

    !!! note
        For the **BOM** explosion, the system considers the following Assembly Types: Explicit, Explicit Long Running, Automatic At Track In, Automatic At Track Out, Packing, Weigh and Dispense and Mixed.

3. If the **Product** has the Include In Schedule set as `true`, Scheduling Mode is `Production Order` and the **Production Order** has the Include In Planning = `true`, choose whether to perform a synchronization of the Production Order Steps through which this **Production Order** will be fulfilled. For more information, see [Synchronize Production Order Steps](synchronize_production_order_steps.md).
4. Select **Start** to complete the transaction.

!!! note
    When in planning mode, the default Flow Path starts from the Production Order instead of from the Product.
