At Cyprus-Amax, we had a heavily modified version of 3.013. We did supplier archiving on a regular basis. We had problems, but not bad enough to prevent us from using the feature.
The biggest problem I remember was that archiving left FPAs in a corrupted state. Cleaning up catalog items and suppliers left FPAs in a 'stuck' state if there was an incomplete FPA for the part/supplier.
We were able to clean up using the de-archive feature then correcting the items, but the problem caused the batch program to fail, and end-users were unaware of the problem. Programmers needed to determine who the buyer was to get the problem corrected before batch processing could complete.
Note, however, that Cyprus was running a customized version of the archiving program that may have been the cause of the problem.
