Query - Pivoting 2 columns into 2 rows
You could do something like this I suppose:

DECLARE @EndDate DATE
SET @EndDate ='20160728' --{?EndDate}

SELECT 
    A.LineType,
    CASE B.ItemCode WHEN 'FG/RM/001' THEN CASE A.LineType WHEN 'Litres' THEN SUM(B.IssuedQty) WHEN 'Tons' THEN SUM(B.CmpltQty) ELSE Null END END AS [FG/RM/001],
    CASE B.ItemCode WHEN 'FG/RM/002' THEN CASE A.LineType WHEN 'Litres' THEN SUM(B.IssuedQty) WHEN 'Tons' THEN SUM(B.CmpltQty) ELSE Null END END AS [FG/RM/002],
    CASE B.ItemCode WHEN 'FG/RM/003' THEN CASE A.LineType WHEN 'Litres' THEN SUM(B.IssuedQty) WHEN 'Tons' THEN SUM(B.CmpltQty) ELSE Null END END AS [FG/RM/003],
    CASE B.ItemCode WHEN 'FG/RM/004' THEN CASE A.LineType WHEN 'Litres' THEN SUM(B.IssuedQty) WHEN 'Tons' THEN SUM(B.CmpltQty) ELSE Null END END AS [FG/RM/004],
    CASE B.ItemCode WHEN 'FG/RM/005' THEN CASE A.LineType WHEN 'Litres' THEN SUM(B.IssuedQty) WHEN 'Tons' THEN SUM(B.CmpltQty) ELSE Null END END AS [FG/RM/005],
    CASE B.ItemCode WHEN 'FG/RM/006' THEN CASE A.LineType WHEN 'Litres' THEN SUM(B.IssuedQty) WHEN 'Tons' THEN SUM(B.CmpltQty) ELSE Null END END AS [FG/RM/006],
    CASE B.ItemCode WHEN 'FG/RM/007' THEN CASE A.LineType WHEN 'Litres' THEN SUM(B.IssuedQty) WHEN 'Tons' THEN SUM(B.CmpltQty) ELSE Null END END AS [FG/RM/007]
FROM 
    (
        SELECT 'Litres' AS LineType
    UNION ALL
        SELECT 'Tons' AS LineType
    ) A
CROSS JOIN 
    (
        SELECT T1.ItemCode,SUM(T0.IssuedQty) [Litres],SUM(T1.CmpltQty) [Tons]
        FROM    WOR1 T0 INNER JOIN
                OWOR T1 ON T0.DocEntry = T1.DocEntry INNER JOIN
                OITM T2 ON T1.ItemCode = T2.ItemCode
        WHERE   T0.ItemCode ='FURNACE OIL/0001' AND T1.Type ='S' AND 
                (T1.PostDate BETWEEN (SELECT Dateadd(month, Datediff(month, 0, @EndDate), 0)) AND @EndDate)
        GROUP BY T1.ItemCode
    ) B
GROUP BY 
    A.LineType
