PARTITION SCHEME values are out of order

i added a new year to a Partition Function and it completed successfully. --ALTER DATABASE dbname ADD FILEGROUP fgname_2018 --ALTER DATABASE dbname ADD FILE filename_2018 --ALTER PARTITION SCHEME DATESKEY_SCHEME NEXT USED RWSBILO_2018; --ALTER PARTITION FUNCTION dateskey () SPLIT RANGE (20171231) -- New Range Command(s) completed successfully. When I script both the partition scheme the values are out of order 1) does it matter? if so what do i need to do? CREATE PARTITION SCHEME [DATESKEY_SCHEME] AS PARTITION [DATESKEY] TO ([2013], [2014], [2015], [2016], [2018], [2017])
