1Version family19935Message classReconciliation2Functionadvice3Origin indicatorIssuer repeatReconciliation messages exchange information used to compare processing records. They belong to a different message class from authorization or a financial transaction.
What this function tells you
An advice carries information under the connection’s advice procedure. An advice is a distinct function, not another name for a request.
The final digit marks a repeat for the stated origin category. Follow the connection’s duplicate handling rules; do not create an unrelated new transaction when processing a repeated message.
Before acting on the message
Compare the agreed period, totals and identifiers. Receipt of a reconciliation message alone does not confirm a bank deposit.
This entry follows the 1993 column of Moov’s listed message types. It does not claim that every network supports this message or that a newer standard uses an identical field layout.
Source scope and interpretation
The prose mentions 2007 where its version table and examples use 2003. This reference uses the explicit example column and does not label it as the 2023 edition.
Some usage descriptions conflict with the digits. For example, the source labels 0320 as a request, while its function digit 2 denotes advice. Several response rows also describe a direction that conflicts with the request exchange. This reference explains the components and does not reuse those usage sentences or assert a universal direction of travel.
