SELECT @query = 'SELECT Product
  FROM 
  #WeeklyBreakupData
  UNPIVOT
    Producta FOR Product IN (' + STUFF(@ListWeekData, 1, 1, '') + ')
  ) AS up;';
PRINT @query;
 EXEC (@query);
drop table #WeeklyBreakupData
but unable to get the desired result. Please help me out ASAP.

Here you go
CREATE TABLE tmp (Name CHAR(1),Forecast INT,Stock INT)
INSERT tmp SELECT 'a',100,300  
INSERT tmp SELECT 'b',300,400 
INSERT tmp SELECT 'c',200,250
INSERT tmp SELECT 'd',200,300
-- dynamic pivot (SQL Server 2005/2008)
DECLARE @pivot_cols NVARCHAR(1000);
SELECT @pivot_cols =
        STUFF((SELECT DISTINCT '],[' + Name
               FROM tmp
               ORDER BY '],[' + Name
               FOR XML PATH('')
               ), 1, 2, '') + ']';
DECLARE @pivot_query NVARCHAR(2000);
SET @pivot_query =
N'SELECT * FROM (
SELECT * FROM (
SELECT Name,SUM(Forecast) Forecast,SUM(Stock) Stock FROM tmp
GROUP BY Name ) tmp UNPIVOT
 Col for [GROUP] IN (Forecast,Stock)
) as UnPvt ) pvt
PIVOT (MAX(Col) FOR Name IN (' + @pivot_cols + ')) j'
EXEC(@pivot_query);
