XMLData.value('(Log/EntryDate)[1]','datetime') as EntryDate,
XMLData.value('(Log/SpecialistID)[1]','int') as SpecialistID,
XMLData.value('(Log/HoursData)[1]','decimal(18,2)') as HoursData,
XMLData.value('(Log/UpdatedBy)[1]','varchar(max)') as UpdatedBy,
XMLData.value('(Log/Options)[1]','varchar(max)') as Options,
logdate
FROM dbo.EditedHourSheetLog
GROUP BY HourSheetID,
XMLData.value('(Log/EntryDate)[1]','datetime'),
XMLData.value('(Log/SpecialistID)[1]','int'),
XMLData.value('(Log/HoursData)[1]','decimal(18,2)'),

This way i achieve my task
ALTER PROC sp_HourSheetLog
(
#StartDate VARCHAR(8),
#EndDate VARCHAR(8)
)
AS
SELECT B.ID
,A.RowID
,B.EntryDate
,B.Name
,B.HoursData
,B.UpdatedBy
,Options=(CASE B.Options
WHEN 'rdLeave' THEN 'Leave'
WHEN 'rdsick' THEN 'Sick'
WHEN 'rdSalvage' THEN 'Salvage'
WHEN 'rdCSRDuty' THEN 'CSR Duty'
WHEN 'rdShippingSales' THEN 'Shipping and Sales'
WHEN 'rdEOL' THEN 'EOL'
WHEN 'rdTraining' THEN 'Training'
WHEN 'rdOther' THEN 'Other'
END)
,B.ModDate
FROM (
(
SELECT HourSheetID,(MAX(RowID)+1) as "RowID"
FROM EditedHourSheetLog l,EditedHourSheet h
GROUP BY HourSheetID
) A
JOIN
(
SELECT h.ID
,s.Name
,h.EntryDate
,h.HoursData
,h.Options
,h.UpdatedBy
,h.ModDate from EditedHourSheet h
LEFT JOIN Specialists s
ON h.SpecialistID=s.SpecialistID
) B
ON A.HourSheetID=B.ID
)
WHERE Convert(Varchar,ModDate,112)>=#StartDate AND
Convert(Varchar,ModDate,112)<=#EndDate
UNION
(
Select HourSheetID as ID,RowID,
XMLData.value('(Log/EntryDate)[1]','datetime') as EntryDate,
--XMLData.value('(Log/SpecialistID)[1]','int') as SpecialistID,
s.Name,
XMLData.value('(Log/HoursData)[1]','decimal(18,2)') as HoursData,
CAST(XMLData.value('(Log/UpdatedBy)[1]','varchar(max)') AS VARCHAR(MAX)) UpdatedBy,

END),
LogDate as ModDate
FROM EditedHourSheetLog h
LEFT JOIN Specialists s
ON h.XMLData.value('(Log/SpecialistID)[1]','int')=s.SpecialistID
WHERE Convert(Varchar,LogDate,112)>=#StartDate AND
Convert(Varchar,LogDate,112)<=#EndDate
)
ORDER BY ID,RowID DESC
--sp_HourSheetLog '20140101','20140326'

You can use a derived table and do the group by in the main query.
SELECT T.HourSheetID,
MAX(T.RowID)+1 as RowID,
T.EntryDate,
T.SpecialistID,
T.HoursData,
T.UpdatedBy,
T.Options,
T.logdate
FROM (
SELECT HourSheetID,
RowID,
XMLData.value('(Log/EntryDate)[1]','datetime') as EntryDate,
XMLData.value('(Log/SpecialistID)[1]','int') as SpecialistID,
XMLData.value('(Log/HoursData)[1]','decimal(18,2)') as HoursData,
XMLData.value('(Log/UpdatedBy)[1]','varchar(max)') as UpdatedBy,
XMLData.value('(Log/Options)[1]','varchar(max)') as Options,
logdate
FROM dbo.EditedHourSheetLog
) AS T
GROUP BY T.HourSheetID,
T.EntryDate,
T.SpecialistID,
T.HoursData,
T.UpdatedBy,
T.Options,
T.logdate
