Let’s start with what exactly the Business Central ENUM is. Those who come from an object-oriented programming background might already know what the enums are. enums are objects that are essentially a read-only list of items. Another change with the Business Central is that lists begin with the number 0. It goes for Business Central enums as well, so you can refer to specific items both by name and number. If you want to choose the first element, then type in 0 or the element’s name.
