MSATS / B2B Retail Market Transaction

Detects AEMO MSATS retail-market transaction content - aseXML transaction names (CATSChangeRequest, NMIDiscoveryRequest/Response, ServiceOrderRequest/Response, MeterDataNotification), CATS change-request codes (e.g. CR1000/CR1060, CR4050/1, CR5050/1), and role-coded NMI standing data (FRMP/LNSP/MDP with an NMI). These artefacts carry customer transfer, metering and consumption context regulated under the retail market procedures.

Confidence

Confidence justification

Medium confidence: aseXML transaction names are near-unique to AEMO retail market messaging; the role-acronym+NMI arm is looser and relies on proximity. Procedure documents legitimately use the same vocabulary, so enforcement needs volume thresholds or data-bearing corroboration.

MSATS, change request, meter data, datastream, retail transfer, standing data, B2B

Proximity: 300 characters

Should match

• <ase:Transaction><CATSChangeRequest><NMI>3120000000</NMI></CATSChangeRequest> — aseXML CATS change request payload
• lodge a ServiceOrderRequest so the FRMP is allocated in MSATS — B2B service order transaction name
• CATS CR 1060 raised to correct the standing data — Labelled CATS change request code
• the FRMP for this NMI transfers on the next business day — Role acronym in proximity to NMI

Should not match

• the CR 1060 form is in the HR folder — CR code without CATS labelling
• send the service order to the plumber tomorrow — Generic service-order prose
• FRMP is one of several market roles — Role acronym without NMI proximity or transaction vocabulary

Known false positives

• AEMO procedure documents, participant training packs and vendor integration guides quote transaction names and CR codes without customer data. Mitigation: Require corroborative keywords, use count thresholds in DLP rules, and exclude published procedure repositories by location scoping.
