Question

select problemrecordedbytitle,problemstatus ,
       count(problemstatus) from problemtable 
where problemrecordedccyy >='2011'
and problemrecordedbytitle like 'LPM%'
group by problemrecordedbytitle, problemstatus
order by problemrecordedbytitle asc

LPM-AMS-EDW Open    1
LPM-AMS-EDW WIP     1
LPM-AMS-EOM Closed  4

this sql provides me with nice summary of statuses. however i got a new requirement today.

i want to sum of all ie count(problemstatus) and count(problemstatus<>closed) in summary.
it should be like

LPM-AMS-EDW    NotClosed    2
LPM-AMS-EDW    Total        6

I am not sure how i can do it in TSQL

You really should be careful not to group on fields with different values.
This will give you the result you are looking for as described.

;WITH a as(
SELECT problemrecordedbytitle,problemstatus from problemtable  
WHERE problemrecordedccyy >='2011' 
and problemrecordedbytitle like 'LPM%' 
)
SELECT problemrecordedbytitle, 'NotClosed', COUNT(*) FROM a WHERE problemstatus <> 'Closed' 
GROUP BY problemrecordedbytitle
UNION ALL
SELECT MIN(problemrecordedbytitle), 'Total', COUNT(*) FROM a

I would rewrite it to this to prevent those group problems:

declare @problemtable table (problemrecordedbytitle varchar(20), problemstatus varchar(10))

INSERT @problemtable values('LPM-AMS-EDW', 'Open')
INSERT @problemtable values('LPM-AMS-EDW','WIP')
INSERT @problemtable values('LPM-AMS-EOM','Closed')
INSERT @problemtable values('LPM-AMS-EOM','Closed')
INSERT @problemtable values('LPM-AMS-EOM','Closed')
INSERT @problemtable values('LPM-AMS-EOM','Closed')

;WITH a as(
SELECT left(problemrecordedbytitle, 3) problemrecordedbytitle,problemstatus 
FROM @problemtable -- replace this tablename for your script 
-- You need these lines for your script
-- WHERE problemrecordedccyy >='2011' 
-- and problemrecordedbytitle like 'LPM%' 
)
SELECT problemrecordedbytitle, 'NotClosed' [status], COUNT(*) count FROM a WHERE problemstatus <> 'Closed' 
GROUP BY problemrecordedbytitle
UNION ALL
SELECT MIN(problemrecordedbytitle), 'Total', COUNT(*) FROM a

Result:

problemrecordedbytitle status    count
---------------------- --------- -----------
LPM                    NotClosed 2
LPM                    Total     6
