Discontinued message (7, 8, 9, 11 or 12) sent under Release 2027
Symptom
The receiver on Release 2027 does not know the message type: 404 on the endpoint or a rejection on afdDefinitionName.
Cause
Messages 00551, 00552a, 00552b, 00554 and 00555a only exist up to and including Release 2026 (schema 001.04).
Fix
Migrate to the Release 2027 flows: control information via message 10, unit values via message 13, reconciliation bilaterally. As long as the chain works on Release 2026, state afdDefinitionVersion 001.04.
