CDRN join miss is not OI unmatched
Divide unmatched CDRN alerts by CDRN alerts in one Verifi cut. That ratio is join-miss %.
Pair: CDRN-match miss share on Chargebacks. OI twin: OI unmatched. Ethoca twin: order-match miss.
What you type
Unmatched CDRN alerts — Visa CDRN alerts with no CRM / gateway join in the cut.
CDRN alerts — Visa CDRN alerts in that same Verifi cut.
Join-miss % = unmatched CDRN alerts ÷ CDRN alerts × 100. Fat join-miss % usually means ARN / amount / descriptor drift — chase those keys; never invent a join-miss chip.
What not to do
Skip inventing join-miss %. Skip dumping OI unmatched into CDRN fields. Skip treating Ethoca no-joins as Visa CDRN misses. Skip blending MIDs when one seat owns the unmatched pile.
