# Track-In Sub-Material

## Overview

This operation is used to track in a **Sub-Material** into a **Resource**, meaning that the **Sub-Material** begins being processed at the physical **Resource**. This operation can be performed from both the **Material** and **Resource** perspectives.

## Setup

No specific setup is required other than meeting the preconditions of the transaction.

## Preconditions

* The **Sub-Material** is in `Queued` or `Processed` state.
* The **Resource** into which the **Sub-Material** is being tracked in is a **Sub-Resource** of Processing Type `Process` of the **Resource** where the **Parent Material** is located. If the **Resource** where the **Parent Material** is located does not have **Sub-Resources** of Processing Type `Process`, the **Resource** must be `null`.
* The **Parent Material** is in `In Process` state.
* The current **Step** `SubMaterialTrackStateDepth` property is greater than or equal to the current **Sub-Material** depth, and the **Parent Material** `LastProcessedResource` has the `IsSubMaterialTrackingEnabled` property set to `true`.

## Sequence of Steps

### Step 1: Resource State

1. Select the **Sub-Material** and select **Track-In**.
2. Verify the **Resource** details and define the **Resource State**.
3. Click **Next**.
