Description

The Business Message Reject 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 (35=3) message should be issued.

The only exception to this rule is when a transport other than the FIX session protocol is being used (transport independence). An appropriate reject message of the given session protocol or the Business Message Reject message should be used instead.

See the session-level Reject (35=3) message

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

Situation Appropriate Response

Note the only exceptions to this rule are:

  1. 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 BusinessMessageReject <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.
  2. In the event a valid business message is received, fulfills session-level rules, however, the message type is not supported by the receipient. In this situation a BusinessMessageReject <j> with BusinessRejectReason <380> = "Unsupported Message Type" can be issued if the system is unable to send the specific "reject" message listed above because the receiving system cannot generate the related "reject" message.
  3. In the event a business message is received, fulfills session-level rules, but lacks a field conditionally required by the FIX specification. In this situation a BusinessMessageReject <j> with BusinessRejectReason <380> = "Conditionally Required Field Missing" can be issued if the system is unable to send the specific "reject" message listed above. One example of this would be a stop order missing StopPx. However, a Business Message Reject message MUST NOT be used to enforce proprietary rules more restrictive than those explicit in the FIX specification, such as a broker requiring an order to contain an Account, which the FIX specification considers an optional field.

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

Scenarios for BusinessMessageReject <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

Whenever possible, it is strongly recommended that the cause of the failure be described in the Text <58> field (e.g. "UNKNOWN SYMBOL: XYZ").

372 RefMsgType Y The MsgType of the FIX message being referenced.
1130 RefApplVerID N Recommended when rejecting an application message that does not explicitly provide ApplVerID <1128> on the message being rejected. In this case the value from the DefaultApplVerID <1137> or the default value specified in the NoMsgTypes repeating group on the logon message should be provided.
1406 RefApplExtID N Recommended when rejecting an application message that does not explicitly provide ApplExtID <1156> on the rejected message. In this case the value from the DefaultApplExtID <1407> or the default value specified in the NoMsgTypes repeating group on the logon message should be provided.
1131 RefCstmApplVerID N Recommended when rejecting an application message that does not explicitly provide CstmApplVerID <1129> on the message being rejected. In this case the value from the DefaultCstmApplVerID <1408> or the default value specified in the NoMsgTypes repeating group on the logon message should be provided.
379 BusinessRejectRefID N The value of the business-level "ID" field on the message being referenced. Required unless the corresponding ID field (see list above) was not specified.
380 BusinessRejectReason Y Code to identify reason for a Business Message Reject message.
58 Text N Where possible, message to explain reason for rejection
354 EncodedTextLen N Must be set if EncodedText field is specified and must immediately precede it.
