Why query with MAX(Date) dosen't return any record? - sql

Question

I have a sql query like below:
SELECT CPH.CheckPointID,
CPH.ID AS Check_Point_History_ID,
CLCP.SequenceNo AS Sequence,
CP.Code AS Point_Code,
CPV.ID,
TT.Medium AS Description,
[TEXT_TRANSLATION_ANS].[Medium] AS Value,
CPH.Value_ AS Additional_Information,
EMP.NAME AS Checked_By,
CPH.AnsweredOn AS Checked_On
FROM CHECK_LIST_HISTORY CLH
LEFT JOIN CHECK_POINT_HISTORY CPH
ON CLH.ID = CPH.CheckListHistoryID
INNER JOIN (
SELECT CPH2.CheckPointID,
MAX(CPH2.AnsweredOn) AS MaxDate
FROM CHECK_LIST_HISTORY CLH2
LEFT JOIN CHECK_POINT_HISTORY CPH2
ON CLH2.ID = CPH2.CheckListHistoryID
GROUP BY CPH2.CheckPointID
) tm
ON CPH.CheckPointID = tm.CheckPointID
AND CPH.AnsweredOn = tm.MaxDate
LEFT JOIN CHECK_POINT CP
ON CPH.CheckPointID = CP.ID
LEFT JOIN CHECK_POINT_VALUE CPV
ON CPH.CheckPointValueID = CPV.ID
LEFT JOIN TEXT_TRANSLATION TT
ON CP.TextID = TT.TextID
AND TT.LanguageID = LanguageID
LEFT JOIN CHECK_LIST_CHECK_POINT CLCP
ON CP.ID = CLCP.CheckPointID
LEFT JOIN EMPLOYEE EMP
ON CPH.EmployeeID = EMP.ID
LEFT JOIN [TEXT_TRANSLATION] [TEXT_TRANSLATION_ANS]
ON CPV.AnswerTextID = [TEXT_TRANSLATION_ANS].[TextID]
AND [TEXT_TRANSLATION_ANS].[LanguageID] = TT.LanguageID
LEFT JOIN [TEXT_TRANSLATION] [TEXT_TRANSLATION_RES]
ON CPV.ResponseTextID = [TEXT_TRANSLATION_RES].[TextID]
AND [TEXT_TRANSLATION_RES].[LanguageID] = TT.LanguageID
WHERE CLH.WipOrderNo = 304
AND CLH.WipOrderType = 26
AND CLCP.WorkCenter = 'WC03'
AND CLCP.Facility = 'C1P1'
This query should return me two records with maximum date, but it returns nothing. I think the problem is in the INNER JOIN because when the line with the INNER JOIN is commented, the query returns the following table:
