When I want to add a new Expense, I can choose between three options: Mileage, Entertainment and Other Expense.
No values are offered for the Entertainment option, even though they are available in the configuration “Expense Rule”.


As I understand it, a function is used here that fills the selection box with data via a filter. Unfortunately, I haven't been able to find anything on how to add data for the Entertainment option.
Many thanks for your help
