# Configuration

This section covers only the configuration that is specific to **Carriers**. Assume the base model, such as **Calendars**, **Facilities**, and **Areas**, already exists.

Use the [Master Data file](masterdata/carriers_management_masterdata.xlsx) to load the model for this tutorial uses.

## Configure the Model

To build a scenario for **Carriers**, you need the following configurations:

1. Create **Product**s of **Product Type** `Carrier` for SemiFG Carriers and Frames. In this example, the products are named `SemiFGCarriers` and `Frames`.

    ![Screenshot showing the SemiFGCarriers product configured with Product Type Carrier.](images/configuration_carrier_product.png)

2. Define the **Flows** and **Steps** that create and store each **Carrier** **Product**, ready for an operator to pick up and attach to a **Material**. In this example:

    - The `Flow Carrier` creates and stores SemiFG Carriers.
    - The `Flow-Frames` flow creates and stores Frames.

3. Fill in the **MaterialCarrierContext** table, where you define the context rules that allow you to associate Carriers with **Material**s. For each **Step** specify:

      - The **Carrier Product** to attach or remove
      - The **Source Step** to pick it up from.
      - The **Operation**. One of the following:
          - `Add`
          - `Remove`
      - The **Assignment Mode**. One of the following:
          - `Main Material`.
          - `Sub Material`.
      - Optionally set **Allow Shared Carriers**
      - Optionally set **Track Used Quantity**.

    !!! info
        If the **MaterialCarrierContext** table does not contain any context rules, you cannot associate carriers with materials.

4. Optionally, define a **Material BOM** with **Scope** set to `Materials` to formalize the physical assembly step. For example, associating the semi-finished material with its carrier at a `Bonding` **Step**.

    ![Screenshot showing the Material BOM associating the semi-finished wafer with its carrier at the Bonding step.](images/configuration_carrier_bom.png)

5. Select the **Carrier Material Verification Mode**, which defines when the system checks that the Material has the correct Carrier. For example, `At Move Next` or `At Track Out`.

## Material and Carrier flows

In this configuration, the system creates a lot of `SemiFG`. Then, the **Material** of **Product** `SemiFG`:

1. Picks up a SemiFG **Carrier**.
2. Obtains a Frame at `Lamination` that carries two **Carriers** simultaneously.
3. Finally loses the SemiFG **Carrier** at `Delamination`, while the Frame continues with the **Material** onward.

This illustrates the multi-carrier and multi-step persistence behavior that the previous section described.

The system automatically removes the second **Carrier**, Frames, when it consumes and terminates `SemiFG` at the `Bonding` **Step**.
