# Scenario 2: Exclusive Usage

Use this scenario to validate the **Exclusive Usage** flag. An **Instrument** marked as exclusive can be associated with only one process **Resource** at a time.

1. Go to `Measurement Station 01` > **Instruments** > **Manage**. For more information, see [[user-guide-manage-resource-instruments]].
1. Start **Dispatch** and **Track-In** for `PCB-LOT-002`.
1. Select :material-plus:, choose `Scale-1`, confirm that **Exclusive** is set to `Yes`, and select **Update**.

1. Go to `Measurement Station 02` > **Instruments** > **Manage**.
1. Select :material-plus: and try to add `Scale-1`.
1. Verify that the system blocks the association.

1. Go to **Business Data** > **Resource** > `Scale-1`.
1. Select **Views** > **References** > **Where Used**.
1. Confirm that `Scale-1` is related to `Measurement Station 01`.

1. Return to `Measurement Station 01` > **Instruments** > **Manage** and remove `Scale-1`.
1. Go back to `Measurement Station 02` > **Instruments** > **Manage**.
1. Add `Scale-1` again and select **Update**.
