Thank you very much for the help. If there is a link between the credit note and return will they appear on the same line? I am looking through the results but do not see any returns with an associated credit memo. I modified your query to display all return documents, but none of them display the related credit memo. Please let me know if I am missing anything:
SELECT T1.[CardName] as 'Customer Name', T12.DocNum AS 'Return No', T12.DocDate as 'Return Date',
T7.DocNum as 'Credit Note No.', T7.DocDate as 'Credit Note date'
FROM RDR1 T0
INNER JOIN ORDR T1 ON T0.DocEntry = T1.DocEntry
Left outer join DLN1 T2 on T2.BaseEntry = T0.DocEntry and T2.BaseLine = T0.Linenum
Left outer join ODLN T3 on T2.DocEntry = T3.DocEntry
Left Outer join INV1 T4 on T4.BaseEntry = T3.DocEntry and T4.BaseLine = T2.Linenum and T4.BaseType = 15 OR (T4.Basetype=17 and T4.BaseEntry=T0.DocEntry and T4.BaseLine=T0.LineNum)
LEFT outer join RDN1 T11 on T11.BaseEntry = T2.DocEntry and T11.BaseLine = T2.LineNum
LEFT outer join ORDN T12 on T11.DocEntry = T12.DocEntry

left outer join OSLP T9 on T9.SlpCode = T1.SlpCode
left outer join OHEM T10 on T10.empID = T1.OwnerCode
WHERE T1.[DocDate] >=[%0] and T1.[DocDate] <=[%1]
AND T12.[DocNum] IS NOT NULL
