# Removing a Carrier

This tutorial describes how to remove one of two carriers attached to a **Material**, while the other carrier stays attached and continues with the **Material**. Consider the `Delamination` **Step** at the `SemiFG` **Flow**.

## Preconditions

- The `SemiFG.01` material already has two carriers attached:
    - The SemiFG carrier, attached at the `SemiFGLotCreation` step.
    - The Frame, attached at the `Lamination` **Step**.
- The `SemiFG.01` material has reached the `Delamination` step.
- A **Material Carrier Context** entry defines a `Remove` **Operation** for SemiFG Carriers at the `Delamination` **Step**.

- The **Carrier Material Verification Mode** is set to `At Track Out`.

If the operator does not remove the SemiFG carrier from `SemiFG.01` before it tracks out, the system prevents the **Track-Out** action and displays an error indicating that the operator must, first, remove the carrier.

## Sequence of Steps

### 1. Open the `Delamination` step

Login to MES and proceed as follows:

1. On the left side menu, select **Business Data**.
2. On the **Business Data** panel, select **Step**.
3. In the search box, type `Delamination`.
4. Select the corresponding step from the search results.

### 2. Remove a carrier

1. On the top ribbon, select the **Step View** tab.
2. On the Materials table, select the `SemiFG.01` checkbox.
3. On the top ribbon, select **More**.
4. On the dropdown menu, select **Manage** from the **Carrier Materials** section.
5. Select the garbage can icon next to the sub-material to remove the carrier.
6. Select the **Save** button to save the change.

## Result

After removal, the SemiFG carriers, the operator can track out the `SemiFG.01` material. The the carriers change to `Queued` state and the operator can reuse them in another step.

The second carrier remains attached and continues with the material to `SemiFGStorage`.
