RELATED CONCEPT
ISO 20022
ISO 20022 is an international, open financial messaging standard based on an extensible XML and JSON data dictionary, unifying cross-border, securities, and high-value payments globally.
FINANCIAL INFRASTRUCTURE CONCEPT
pacs.002
pacs.002 is the ISO 20022 Payment Status Report message used by agents to communicate acceptance, rejection, or other processing statuses for a payment instruction.
Architectural context & analysis
Status reports drive exception queues and customer updates but are not themselves cash settlement evidence.
Reason codes should be preserved verbatim in audit logs and mapped carefully into internal Protocol 201.3 states.
Worked operational scenario
A pacs.002 with RJCT and an invalid beneficiary account code parks the case in a repair queue without marking funds settled.
Implementation considerations & controls
Treat duplicate pacs.002 deliveries as idempotent updates correlated by UETR and instruction IDs.
