Tag # Field Name Req’d Data type Comments

This tag must always be the last field in a message (i.e. it serves, with the trailing <SOH>, as the end-of-message delimiter).

Message Notes

The Business Message Reject (j) message is used by the TT FIX whenever it rejects an application-level message that fulfills session-level rules but cannot be rejected via any other means (i.e. Order Cancel Reject (9) message).

For example, suppose a FIX client sends an Order Cancel/Replace Request (G) message where Tag 11 (ClOrdID) matches an existing client order ID. When TT FIX receives the message, it verifies the validity of the message. However, business rules require that a client order ID remains unique for the trading session. Therefore, TT FIX responds with a Business Message Reject (j) message.
