**Items Revenue Center**

Select from the list the Maitre'D revenue center where these external sales will be posted to.

{% hint style="info" %}
NOTE: Because External Sales can only be linked to one revenue center, this field becomes grayed out as soon as you link one external sale item code to a sale item of the selected revenue center. The field will become available again if you remove all sales items links.
{% endhint %}

Enter the code of the external sales item.

**Internal value**

Select the Maitre'D sales item from the list.
