fix协议介绍8-Reject消息

FIX.5.0SP2 Message

Reject [type '3']

The reject message should be issued when a message is received but cannot be properly processed due to a session-level rule violation. An example of when a reject may be appropriate would be the receipt of a message with invalid basic data which successfully
passes de-encryption, CheckSum and BodyLength checks.

Added FIX.2.7

MsgType = 3

	45	RefSeqNum	@RefSeqNum		MsgSeqNum of rejected message
	371	RefTagID	@RefTagID		The tag number of the FIX field being referenced.
	372	RefMsgType	@RefMsgTyp		The MsgType of the FIX message being referenced.
	1130	RefApplVerID	@RefApplVerID		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	@RefApplExtID		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	@RefCstmApplVerID		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.
	373	SessionRejectReason			Code to identify reason for a session-level Reject message.
	58	Text	@Txt		Where possible, message to explain reason for rejection
	354	EncodedTextLen	@EncTxtLen		Must be set if EncodedText field is specified and must immediately precede it.
	355	EncodedText	@EncTxt		Encoded (non-ASCII characters) representation of the Text field in the encoded format specified via the MessageEncoding field.
