Clint,
Like Suda said, this query assumes your have normal business practise.
One more thing to mention, the lower part of union all needs some other change.  Here is the complete query:
SELECT     DISTINCT 'GRPO' AS TYPE, T1.DOCNUM "GRPO/RET#", T3.DOCNUM PO#,T1.CARDCODE, T1.CARDNAME , T1.DOCDATE, T0.ITEMCODE, T0.QUANTITY, T0.PRICE, T0.LINETOTAL, T0.TOTALFRGN, T0.RATE
FROM         PDN1 T0
INNER JOIN OPDN T1 ON T1.DOCENTRY = T0.DOCENTRY
LEFT JOIN POR1 T2 ON T0.BASEENTRY = T2.DOCENTRY
INNER JOIN OPOR T3 ON T2.DOCENTRY = T3.DOCENTRY
WHERE    T1.DOCNUM LIKE '[%0]'
UNION ALL
SELECT     DISTINCT 'RETR', T1.DOCNUM,T3.DOCNUM, T1.CARDCODE, T1.CARDNAME , T1.DOCDATE, T0.ITEMCODE, T0.QUANTITY, T0.PRICE, T0.LINETOTAL, T0.TOTALFRGN, T0.RATE
FROM         PDN1 T0
INNER JOIN OPDN T1 ON T1.DOCENTRY = T0.DOCENTRY
LEFT JOIN RPD1 T2 ON T0.TRGETENTRY = T2.DOCENTRY
INNER JOIN ORPD T3 ON T2.DOCENTRY = T3.DOCENTRY
WHERE    T1.DOCNUM LIKE '[%0]'
