FIX 4.2 : Business Message Reject <j> message

Structure | Related Messages


The Business Message Reject <j> message can reject an application-level message which fulfills session-level rules and cannot be rejected via any other means. Note if the message fails a session-level rule (e.g. body length is incorrect), a session-level Reject <3> message should be issued.

See the session-level Reject <3> message

It should *NOT* be used in the following situations:

Situation Appropriate Response

Session-level problem meeting the criteria
of the session-level Reject <3> message

Use the session-level Reject <3> message (MsgType <35>=3)

In response to

Use the Execution Report <8> message

In response to:

Use the Order Cancel Reject <9> message

In response to:

Use the Don't Know Trade <Q> (DK) message

In response to:

Use the Allocation ACK <P> message

In response to:

Use the List Status <N> message

In response to:

Use the Quote Acknowledgement<b> message

In response to:

Use the Market Data Request Reject <Y> message

In response to:

Use the Security Definition <d> message

In response to:

Use the Security Status <f> message

In response to:

Use the Trading Session Status <h> message

Note the only exception to this rule is in the event a business message is received, fulfills session-level rules, however, the message cannot be communicated to the business-level processing system. In this situation a Business Message Reject <j> with BusinessRejectReason <380> = "Application not available at this time" can be issued if the the system is unable to send the specific "reject" message listed above due to this condition.

Messages which can be referenced via the Business Message Reject <j> message are (the "ID" field BusinessRejectRefID <379> refers to noted in [ ]):

Scenarios for Business Message Reject <j>:

BusinessRejectReason <380>:

  • 0 = Other
  • 1 = Unknown ID
  • 2 = Unknown Security
  • 3 = Unsupported Message Type (receive a valid, but unsupported MsgType <35>)
  • 4 = Application not available
  • 5 = Conditionally Required Field Missing
