[Quickfix-developers] How to manage Required tag missing

[Sutee G. <su...@si...>]

Dear all,
    I develop my fix engine using C#, and I test it with Banzai. I setting
my fix engine following below.

[DEFAULT]
ConnectionType=acceptor
SocketAcceptPort=5001
FileStorePath=store
StartTime=00:00:00
EndTime=23:00:00

[SESSION]
BeginString=FIX.4.0
SenderCompID=XYZ
TargetCompID=CLIENT1
UseDataDictionary=Y
DataDictionary=spec/FIX40.xml
ValidateFieldsOutOfOrder=N
ValidateFieldsHaveValues=N

    How can I manage Require tag missing, when I receive message from
Banzai. In my idea, some tags that define in xml spec are not require. But
when I receive message, it rejects message from banzai. For example code,
that I use in my engine to get some field is

    string sSenderSubID = order.getHeader().getField(new
SenderSubID()).getValue();

    Is this correct?, If It's wrong, please advise me to correct it.

Best Regards,
