# Materials

Materials are the physical components consumed and produced during manufacturing. This includes raw materials, work-in-progress, finished products, and consumables.

The Bill of Materials in each operation segment defines which materials are consumed and produced. Material configuration links closely with [Operations](/tillit/knowledge-base/scheduler/data-templates/operations.md) and [Inventory](/tillit/knowledge-base/scheduler/inventory.md).

## Navigation

***Scheduler*** > ***Data Templates*** > select a template > ***Materials***

## Material Groups

Material groups categorise materials for easier management.

1. Click **Manage Material Groups**.
2. Add, update, or delete groups as needed.

## Creating a Material

1. Click the **+** button next to **Manage Material Groups**.
2. Enter the material details.

## Adding Thresholds

Materials link to inventory tracking. Set minimum and maximum inventory levels to flag low or excess stock positions:

1. Select the material and click the **Settings** icon.
2. Enter the **Min** and **Max** threshold values.

These thresholds are displayed on the [Inventory](/tillit/knowledge-base/scheduler/inventory.md) draw-down graph and drive the status-based filtering colours.

## Material Properties

Material properties are attributes that the organisation wants to track through the scheduling workflow. Properties serve two purposes:

1. **Visualisation and reporting** — display attributes like colour, size, or grouping on the scheduling Gantt chart
2. **Optimisation input** — drive changeover calculations (e.g. switching from red to white plastic requires extra cleaning time)

### Adding a Property

1. Click the **+** button in the **Properties** section.
2. Enter the **Property Name** and **Property Value**.

**Example:** Property Name = "Colour", Property Value = "Red"

You can add as many properties as required. Once created, they are available as optimisation properties in [Changeovers](/tillit/knowledge-base/scheduler/data-templates/changeovers.md) and [Optimisation](/tillit/knowledge-base/scheduler/data-templates/optimisation.md) configuration.
