3. The screen for configuring the **Detection Model** will be displayed:
{% hint style="info" %}
Before configuring the model, understand how the anomaly is detected:
The model calculates the variation in consumption between the current date **(D0)** and the model date **(D-1, D-7 and D-14)** and checks whether the variation is above the value ($) or % configured in the model.
**D-1**: Date of the previous day
**D-7**: Date of 7 days ago
**D-14**: Date of the last 14 days (average of the period)
{% endhint %}
4. Configure the model:
There are two options for configuring the template:
{% tabs %}
{% tab title="Global" %}
The parameters configured in this option are propagated to all registered business anomaly groups.
{% endtab %}
{% tab title="By Anomaly Group" %}
The parameters configured in this option only affect the specific group.
{% endtab %}
{% endtabs %}
* **Global**
* Set a value ($) and a percentage (%) that will be considered reasonable for all added anomaly groups.

{% hint style="info" %}
To select the Notification Group, it is necessary to configure the desired groups within the [Notifications ](https://docs.piercloud.com.br/plataforma-de-finops/finops-platform-english/platform-configuration/setup-features/notifications)functionality, so that they are pre-registered and available for selection.
