[Quickfix-developers] Cancelling and modifiying orders

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

Hi All,

I am cancelling and modifying orders and I have a problem with field 
ClOrdID(11). In both messages (order cancel request - F- and order 
modification request - G), there is the field 11, this will be the new order 
id when the cancellation or modification is made.

But I don't know how to manage this field, I would like that the order Id 
will be the same after the cancellation or modification, but I don't know if 
this is possible. I am tried to put this field with a number by code but the 
message doesn't have the number that I have put in the code, the first 
cancellation or modification has a 1, the problem is that there already 
exist an order identified by 1 and then there is an error because the 
ClOrdId is duplicated.

Anyone knows if I can decide this number? Can I use the same number that the 
order Id? I will have a problem if order changes the id only because of a 
modification or a cancellation is done.

I have been using version 1.12.1 with vb .net

Thanks in advance

Lidia
