[Quickfix-users] How to change settings in the quickfix engine

[C. G. <let...@gm...>]

Hello.

I use the quickfix engine together with a program called OpenQuant.
www.smartquant.com.

I want to change the settings so that tag 41 is not required in a response
message.
I thought I figured it out. I found the path to the .xml file with all the
settings in, I found the relevant message and set the tag required to "N"
instead of "Y".
After this I save the file and restart my application, but the tag is still
required. I get
"Message 301 Rejected: Conditionally Required Field Missing:41"
Is there something else I should be aware of that is(n't) happening?

Also, for some reason in a cancel order message I get a "15=", and the
quickfix engine doesn't seem to like that the tag lacks a value. I'll try to
dicuss
this with MF Global, that I'm connected to, but is there a way to make
quickfix ignore this problem?
