There is no lookup which would have the years connected to months. You can create new object for it with the required columns and import such records. Here is the example of the lookup values http://prntscr.com/qu19a1
Thank you Dean. While we are still discussing about lookups could you please explain what are
"Base Lookup with Value ( Base )" and where we can use them? Also is it possible that for example, I have a set of departments as a lookup. If a user selects the department, the department code must be displayed?
Base lookup it the system entity that is used to define you object as a lookup http://prntscr.com/quk8a1 When creating new object for lookup, you need to specify its parent object as 'Base lookup'. As for the departments lookup, you can use just the same approach as with Moth-Year lookup and use business rules.
