In Tenzo, you can see your sales broken down in many ways. One of them is by Division and Category.
To learn more about what Division and Category are, please visit this article.
Why do I see "Not Available" as a Division/Category?
It may sometimes happen that a considerable amount of your revenue is assigned to a Division or Category called "Not Available".
These come from items in your integration that are not assigned to any Category/Division. The way to fix this is by going to your integration and making sure that all of your items are correctly assigned to the menu structure.
Depending on what integration you use, menu structures are configured differently. You can contact your CSM to learn more about how to configure this or drop us an email at firstname.lastname@example.org.
