# Correlation scenario

> The Correlation Scenario hierarchy in the Correlation Scenario dimension of FRTBCombinedCube, controlling which Basel correlation scenario (High, Medium, Low) applies to the SBM Risk Charge measure

| --------------- | ------------------------------------------------------ |
| **Description** | The correlation scenario selected for the SBM measure. |
| **Dimension**   | Correlation Scenario                                   |
| **Hierarchy**   | Correlation Scenario                                   |
| **Levels**      | \[ALL, Scenario]                                       |

This hierarchy has several members that can be used to change the selected correlation scenario used by the measure `SBM Risk Charge`.

* By default, `AllMember` selects the highest correlation scenario available *for the selected location*.
* `High` selects the high correlation scenario.
* `Medium` selects the medium correlation scenario.
* `Low` selects the low correlation scenario.
* `Reference` selects the highest correlation scenario *at the `ReferenceLocation` level*.

The `ReferenceLocation` is selected with the context value [ReferenceLevel](./referencelevel).
