Al,This intrigues me because it just so happens that I'm working on a project to unarchive history. The current process is to back off the sales history to a separate library at year end.
So far I've merged the last two year's with the current year's history (in a test environment, of course). There are no discernible differences to me (but I'm blind in one eye and can't see too well out of the other one) as far as inquiry goes. The inquiries do ask the requestor for the customer and, optionally, a starting date.
Naturally, if I was reading the sales history as an Input Primary, I would expect things to take longer. Is this what you are talking about, or is there some impact on the random searches (inquiries)? What kind of activity other than the I/P would adversely impact a situation such as this?

Depending on your applications, archiving can dramatically improve performance. Let's suppose for example, people are using an inventory history inquiry program and the history has 10 years of data, but 99% of the people only need to see what is in the last 2 weeks. Having 500 weeks of data in the file can slow access for people who only need to see 2 weeks worth. Archiving solution makes the data available to the 1% applications that need to see 500 weeks, while performance dramatically improved for the 99% of your users. There's bunch of people on these lists who are familiar with the various archiving alternatives and can elucidate further if this interests you. - Al Macintyre http://en.wikipedia.org/wiki/User:AlMac BPCS/400 Computer Janitor ... see http://radio.weblogs.com/0107846/stories/2002/11/08/bpcsDocSources.html
