A variable can be accessed by case type but not a property

Whether we can define a variable can be accessed by everywhere in a case type but not a property?

We would NOT like to make this variable persist (in background database table) after case resolved, because it’s just temporary used during case running, so it’s not worth to be persisted.

Thanks.

@MaxonL16591286 you can open property-> Advanced tab-> scroll below to Persistence

Enable checkbox → Do not save property data
