Unsupportted Message Type

Hello,

I send the FIX Messages whose type is ‘U3’ ( specified by the broker ), but receive the ‘j’/BUSINESSMESSAGEREJECT message.

I checked that I implement the callback function onMessage() to handle the ‘U3’ Message. By the way, ‘U3’ is a custom MessageType.

Yan

Your title says “unsupported message type” but you do not give the value of BusinessRejectReason(380). Assuming they are identical, there may be more information if Text(58) and/or BusinessRejectRefID(379) are provided as well. Otherwise you need to contact your counterparty and ask if their application really supports message type “U3” and what the rules for its fields and valid values are. The FIX session layer has accepted your message and passed it to the application layer that then cannot process the message.
