You have to use LFET JOIN for taible that may nor have records for all suppliers.

SELECT rfq.*, ;
      rfqdetail.rqd_desc, rqd_Linenum, rqd_needby, rqd_reqnum, rqd_qty,;
      quotes.quo_freight, quo_portother, quo_date, quo_daysvalid,;
      quotedetails.qud_delivery, qud_unitcost, ;
      Suppliers.sup_name;
   FROM rfq ;
      INNER JOIN rfqdetail ON rfq_pk = rqd_rfqfk;
      INNER JOIN Suppliers ON quo_suppfk = sup_pk;
      LEFT JOIN quotes ON rfq_pk = quo_rfqfk;
      LEFT JOIN quotedetails ON rqd_pk = qud_rqdfk AND quo_pk = qud_quotefk;
   ORDER BY sup_Name, rqd_LineNum
