通过PO, 找点收单号:

select rsh.receipt_num

from po_headers_all poh,

rcv_shipment_headers rsh,

rcv_shipment_lines rsl,

po_lines_all pol,

po_line_locations_all poll

where

poh.segment1='20600021'

and

poh.po_header_id=pol.po_header_id

and

pol.po_line_id=poll.po_line_id

and

poll.line_location_id=rsl.po_line_location_id

and

rsh.SHIPMENT_HEADER_ID=rsl.shipment_header_id
