what is "unassigned literal" when defining an enumeration attribute in RTC
When you define an enumeration type in RTC, you need to define a default value and an unassigned literal. I understand what the default value is for. I'm not sure about the "unassigned literal". Can anybody explain that to me?
Thanks!

Hi Jeff,
If you want to make an enumeration attribute as a required field, you can define an Unassigned literal. When the enumeration attribute has this Unassigned literal selected, RTC considers the attribute is unset. For a use case, you can see the answer in the post https://jazz.net/forum/questions/72880/enumeration-default-literal
Hope that's helpful.
