purchase order report

I have a report that should prints the image of the products that are in the related purchase order ( print only the images of the products that has the property Imprimir Desenho checked on Quality product requirement)
the code I have in the report is

*Requisito produto Qualidade - OnAfterGetRecord()

IF ReqQualidade.GET("Requisito produto Qualidade".Requisito) THEN
BEGIN
IF ReqQualidade."Imprimir Desenho" THEN
BEGIN
ItemTemp."No.":=PurchLine."No.";
IF ItemTemp.INSERT THEN
BEGIN
ndesenhos+=1;
flagglobal:=TRUE;
END;
END;
END;

*Desenho - OnPreDataItem()
IF NOT flagglobal THEN
CurrReport.BREAK;

Desenho.SETRANGE(Number,1,ndesenhos);
ItemTemp.FINDFIRST;

*Desenho - OnAfterGetRecord()

IF ItemI.GET(ItemTemp."No.") THEN
BEGIN
manufactsetup.GET;
ItemTemp.DELETEALL;
IF filee.OPEN(manufactsetup.Destino+'\'+ItemI.Ficheiros) THEN
BEGIN
filee.CREATEINSTREAM(Instream);
ItemTemp.Picture.CREATEOUTSTREAM(OutStream2);
COPYSTREAM(OutStream2,Instream);
ItemTemp.INSERT;
ItemTemp.CALCFIELDS(Picture);
filee.CLOSE;
END;
END;


The report only prints the first product that has the property Imprimir Desenho checked on Quality product requirement, but it print it as many time as products in the order with that same characteristic.
For example
in an order with 2 products with the requirement "Imprimir Desenho" it only prints the image of the first but 2 times

Can same one tell me where the problem is?
