"SUM" keyword does not show results in query manager

Question

Im using the sql keyword sum in my query which displays sum of doctotal for all sales order created by a particular sales employee.. but it is just showing the doctotal row wise. Is there sum limitations on the sql syntax that can be used?
Also is it possible to show the sum of doctotals without callin it at row level,as we are printing redundant data. Im not using PLD as the requirement is just to show the result of the query.
Please help

Try the query as
select sum(t.total) from
SELECT T0.DocNum, T0.DocTotal,T0.DocTotal - T0.VatSum, T0.DocDate, Sum(T0.DocTotal) as Total,Sum(T0.DocTotal - T0.VatSum) as withoutTax FROM ORDR T0 INNER JOIN OSLP T1 ON T0.SlpCode = T1.SlpCode
WHERE T1.SlpName ='Rajesh Nair' and T1.SlpCode -1
GROUP BY T0.DocNum, T0.DocDate, T0.VatSum, T0.DocTotal
) t
or in one query at the end as sum as
SELECT T0.DocNum, T0.DocTotal,T0.DocTotal - T0.VatSum, T0.DocDate, Sum(T0.DocTotal) as Total,Sum(T0.DocTotal - T0.VatSum) as withoutTax FROM ORDR T0 INNER JOIN OSLP T1 ON T0.SlpCode = T1.SlpCode
WHERE T1.SlpName ='Rajesh Nair' and T1.SlpCode -1
GROUP BY T0.DocNum, T0.DocDate, T0.VatSum, T0.DocTotal
UNION
select null, null, null, null, sum(t.total), null from
SELECT T0.DocNum, T0.DocTotal,T0.DocTotal - T0.VatSum, T0.DocDate, Sum(T0.DocTotal) as Total,Sum(T0.DocTotal - T0.VatSum) as withoutTax FROM ORDR T0 INNER JOIN OSLP T1 ON T0.SlpCode = T1.SlpCode
WHERE T1.SlpName ='Rajesh Nair' and T1.SlpCode -1
GROUP BY T0.DocNum, T0.DocDate, T0.VatSum, T0.DocTotal
) t
