Read the four digits
2Version family20032Message classFinancial transaction2Functionadvice0Origin indicatorAcquirerFinancial transaction messages carry a transaction for processing or report on it. The message function distinguishes a request from an advice or response.
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 origin indicator identifies the origin category of the exchange. In a response, it must not be read as a universal statement about which system sent the current packet.
Before acting on the message
Keep the transaction record, response and settlement records separate. A financial message type does not by itself prove that funds reached a merchant’s bank.
This entry follows the 2003 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.
