We encounter this all the time at work. New customer, so new integration. What's your unique shipment reference? This one? Ok fine. Go into production, and after a few months we get missing shipments. Support check, missing shipments have same reference as old shipments. "Oh, yeah we reuse the references after about 90 days... And, no, we don't have any globally unique references."
This is fun when so much of the flow is based on these references, think goods arrival scanning, and sometimes shipping does take a long time so 90 days or whatever is cutting it close.
