We would like to retire several assets(mass retire

We would like to retire several assets(mass retirement). However, these assets are not in alphabetical order (not in sequence). All I have got in the Oracle manuals is that you can retire these assets but they need to be in sequence e.g asset numbers 1001, 1002, 1003, 1004 etc., my asset numbers are not in sequence e.g. I would like to retire assets numbers 1002, 1009, 1020, 1030, 1040 etc.Somebody with any idea how to go about this? Thank you
