maybe tell us - how the tables look like - how they are related - exacactly what you want and then maybe we could help you. or give some example rows of A and B and what you expect as the output : which rows you want to see, which rows you don't want to see.
I can explain it to you, but i can not understand it for you.
SELECT A.I_PART, A.I_RCPT_CHNG_LVL, A.I_PO, A.X_RCPT_COMNT, A.I_MATL_DOCU, A.Q_GOODS_RECVD, A.D_GOODS_RECVD FROM EPPS.EOGPREC A WHERE NOT EXISTS (SELECT * FROM PRDT.TBPART04 B WHERE A.I_PART = B.PART_NO
