1st
SELECT
ProjectCode,
SUM (- 1 *(CreditAm) +(DebitAm)) AS Balance
FROM
[dbo].[AcDetail]
WHERE
AcCode IN (
401000,
402000,
403000,
404000,
405000,
406000,
407000,
499999
)
AND BranchCode = 'WP'
AND TDate >= '2016-01-01'
AND TDate <= '2016-12-31'
GROUP BY
ProjectCode
2nd
SELECT
ProjectCode,
SUM (- 1 *(CreditAm) +(DebitAm)) AS Materials
FROM
[dbo].[AcDetail]
WHERE
AcCode IN (600001, 600002, 600151)
AND BranchCode = 'WP'
AND TDate >= '2016-01-01'
AND TDate <= '2016-12-31'
GROUP BY
ProjectCode
3rd
SELECT
ProjectCode,
SUM (- 1 *(CreditAm) +(DebitAm)) AS Salaries
FROM
[dbo].[AcDetail]
WHERE

650001,
650005,
650006,

)
AND BranchCode = 'WP'
AND TDate >= '2016-01-01'
AND TDate <= '2016-12-31'
GROUP BY
ProjectCode
ORDER BY
ProjectCode

Answer 1

Use Conditional SUM. Sum the values only when the Accode matches the list
SELECT ProjectCode,
Sum (CASE
WHEN AcCode IN ( '401000', '402000', '403000', '404000',
'405000', '406000', '407000', '499999' ) THEN -1 * ( CreditAm ) + ( DebitAm )
ELSE 0
END) AS Balance,
Sum (CASE
WHEN AcCode IN ( '600001', '600002', '600151' ) THEN -1 * ( CreditAm ) + ( DebitAm )
ELSE 0
END) AS Materials,
Sum (CASE
WHEN AcCode IN ( '650001', '650005', '650006', '650007',
'650008', '650009', '650010', '650020',
'650021', '650022', '650023', '650024',
'650025', '650026', '650027' ) THEN -1 * ( CreditAm ) + ( DebitAm )
ELSE 0
END) AS Salaries
FROM [dbo].[AcDetail]
WHERE AcCode IN ( '401000', '402000', '403000', '404000',
'405000', '406000', '407000', '499999',
'600001', '600002', '600151', '650001',
'650005', '650006', '650007', '650008',
'650009', '650010', '650020', '650021',
'650022', '650023', '650024', '650025',
'650026', '650027' )
GROUP BY ProjectCode

Answer 2

We can done it using OUTER APPLY as well by making different set for each column as below:
SELECT D.ProjectCode,
ISNULL(SUM(B.Balance), 0) AS Balance,
ISNULL(SUM(M.Materials), 0) AS Materials,
ISNULL(SUM(S.Salaries), 0) AS Salaries
FROM [dbo].[AcDetail] AS D
OUTER APPLY (SELECT (- 1 *(CreditAm) +(DebitAm)) AS Balance
FROM [dbo].[AcDetail]
WHERE AcCode IN ('401000', '402000', '403000', '404000',
'405000', '406000', '407000', '499999')
AND AcCode = D.AcCode
AND TDate = D.TDate
AND ProjectCode = D.ProjectCode) AS B --Balance
OUTER APPLY (SELECT (- 1 *(CreditAm) +(DebitAm)) AS Materials
FROM [dbo].[AcDetail]
WHERE AcCode IN ('600001', '600002', '600151')
AND AcCode = D.AcCode
AND TDate = D.TDate
AND ProjectCode = D.ProjectCode) AS M -- Materials
OUTER APPLY (SELECT (- 1 *(CreditAm) +(DebitAm)) AS Salaries
FROM [dbo].[AcDetail]
WHERE AcCode IN ('650001', '650005', '650006', '650007', '650008', '650009',
'650010', '650020','650021', '650022', '650023', '650024',
'650025', '650026', '650027')
AND AcCode = D.AcCode
AND TDate = D.TDate
AND ProjectCode = D.ProjectCode) AS S --Salary
WHERE D.BranchCode = 'WP'
AND D.AcCode IN ('401000', '402000', '403000', '404000', '405000', '406000', '407000',
'499999','600001', '600002', '600151', '650001', '650005', '650006', '650007',
'650008','650009', '650010', '650020', '650021', '650022', '650023', '650024',
'650025','650026', '650027')
AND D.TDate >= '2016-01-01'
AND D.TDate <= '2016-12-31'
GROUP BY D.ProjectCode
ORDER BY D.ProjectCode
