I can’t find that our engine should behave in Following case .
(from the document in FIX 4.3 Volume 2 "FIX Session-level Test Cases and Expected Behaviors"Test Case “10” )

Receive Sequence Reset (Gap Fill) message
with MsgSeqNum = expected sequence number
and NewSeqNum < than expected sequence number

Please tell me.

I am not sure that completely understand your question. Please note that the FIX 4.3 "with Errata 20020920" (the Errata contains typographical adjustments to the original FIX 4.3 spec release) added a new test case (10e):

Receive Sequence Reset (Gap Fill) message with NewSeqNo <= MsgSeqNum
and
MsgSeqNum = to expected sequence number

with Expected Behavior:

Send Reject (session-level) message with message “attempt to lower sequnce number, invalid value NewSeqNum=<x>”

This test case was missing from the original FIX 4.3 spec release. Can you provide more details for your question?

I’m sorry.
The documents that I read is a old one.
I got a new one this morning,and I understood the case.

Thanks a lot.
