NETWORK VALIDATED RULES

Reference must not start or end with a slash '/' and not contain two consecutive slashes '//' (Error code(s): T26).

USAGE RULES

The reference type used to identify the transaction should be in line with the reference types available for the message type requested by the MT549. E.g. a MT549 should not request a MT567 using, as linked transaction reference, a COMM reference type that is not a transaction reference type available for Corporate Action messages.
