I am searching for a solution also. I have worked with JDE for 14_ years now and have had to write archiving and purging routines myself. They have a purge program but it is a file at a time and it saves the purged records off in another library if you are using the AS/400; not sure about any other platform. Let me know what modules you want to have purging/archiving for and when I look at solutions for my needs I will keep yours in mind.
Thanks, Bobby
