enumerate function

enumerate(2023-1990+1)+1990

You can use below logic and get the values from any limit:

a!localVariables(
local!startingYear:1990, /*Instead of hard coding you can use constant*/
local!currentYear: year(now()), /*In your case this value is 2023*/
enumerate(local!currentYear-local!startingYear+1)+local!startingYear
)
