# Does QuickFIX set PreviouslyReported field itself?

I'm using QuickFIX C++ engine in my project.
I send a TradeCaptureReport message to a counter party. There's a field named PreviouslyReported in this message.

I set this value to N in the message but when I check the message that was sent, I see that it is set to Y in the resulting message.

Does QuickFIX set this field itself ignoring the value that I set?

Regards

message.set(FIX::PreviouslyReported(false));
