1Version family19936Message classAdministration2Functionadvice5Origin indicatorOther origin repeatAdministrative messages support protocol administration. The origin indicator in this group identifies another origin category rather than specifically an acquirer or issuer.
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
Use the connection’s operation code and administrative procedure to identify the task. Do not infer a customer payment result from this message class.
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.
