[Quickfix-developers] Field order

[<li...@ho...>]

Hi all,

I am trying to send a DataMarketRequest message, I only want to read the 
futures for IBEX, so I need to use the fiels 50 and 48 to filter the 
information received.

I generated following message:
8=FIX.4.4·9=138·35=V·34=2·49=XXXX·52=20060712-10:12:21.937·56=MEFF·48=21·50=XXX·55=[N/A]·57=M3·146=1·262=0000001·263=1·264=0·265=0·267=1·269=0·461=FXXXSX·10=252·

and the answer is:
8=FIX.4.4·9=127·35=3·34=3·52=20060712-10:15:01·49=MEFF·50=M3·56=A880·57=351·45=2·373=99·58=%MFEMC1FNS-Field 
not supported or misplaced [48=21]·10=081·

I have asked to MEFF (which provides the connection to market using fix) and 
the technical service told me that the problem is the field order. He said 
that I must generate the field 50 before the 48 because 50 is a header field 
and It must be before.

The problem is that I am using a QuickFix44.   message and I can't (or I 
don't know how) control the field order.
