This seems to do nothing

I have been debugging new AX2009 to which we migrated recently, and sometimes it is a real fun!

if (numberOfTransOpen == 1 ||
            (numberOfTransOpen > 1 && !printPaymentSchedule))
        {
            // this seems to do nothing
            if (printPaymentSchedule)
            {
                select firstonly tmpCustVendTransOpen;
            }
