Error on change RangeBegin Properties on run time

edited November 2004 in Datapipelines
I try to change properties rangebegin and rangeend of TppDBPipeline
Example Code :

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ppDB, ppDBPipe, StdCtrls, Buttons, ppComm, ppRelatv, ppProd,
ppClass, ppReport;

type
TForm1 = class(TForm)
ppReport1: TppReport;
BitBtn1: TBitBtn;
ppDBPipeline1: TppDBPipeline;
procedure BitBtn1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.BitBtn1Click(Sender: TObject);
begin
ppDBPipeline1.RangeBegin := rbCurrentRecord;
end;

end.

it error :
Undeclared identifier 'rbCurrentRecord'

What's happen and how to fix this problem ?

Thank
