xmlport tries to update key

Hi all, i am trying to avoid the "Do you confirm you want to change the key that identifies this record" message when running a xmlport.

CLEAR(XMLportFinishing);
CLEAR(Ficheiro);
CLEAR(recFicheirosFinishing);
CLEAR(vFileNumber);
CLEAR(vLastName);
recConfigFinishing.GET;

MARKEDONLY(TRUE);
IF FINDFIRST THEN BEGIN
  
  Ficheiro.CREATE(recConfigFinishing."Pasta de arquivo" +'\'+ recFicheirosFinishing.Nome + '.xml');
  Ficheiro.CREATEOUTSTREAM(FXOutStream);

  XMLportFinishing.fxSetFinishingCodes(recFicheirosFinishing.Nome, vLastName);
  vTeste:=COUNT;
  XMLportFinishing.SETTABLEVIEW(Rec);
  XMLportFinishing.SETDESTINATION(FXOutStream);
  XMLportFinishing.EXPORT();

  
  Ficheiro.CLOSE;
  
  MARKEDONLY(FALSE);
  CLEARMARKS;
END ELSE
  ERROR('Não existem registos seleccionados.');

fxSetFilter(vFilter);
CurrForm.UPDATE;

I get the message at the XMLportFinishing.SETTABLEVIEW(Rec) call.



Any ideas?

Thanks in advance.
