To make the usage of Expenses more convenient and the data more readable, You can adjust the setting of expense types. For that, go to Settings -> Expenses types -> Activate/Deactivate different types depending on Your needs. By default all the types are activated.

If You deactivate the expense type, this specific type will not be displayed in the expense type dropdown on expense/cost allocation creation. Moreover, these types will be hidden on Expense tab in Unit and Building page as well as Unit expenses excel.
