Now test the stored procedure

DECLARE @return_value int,

@TotalAmount decimal(38, 2)

EXEC  @return_value = [dbo].[USP_Rpt_GetTotalAmountFromGLAmountByGLCategoryForCFY]

            @Days = 120,

            @G_LCategoryCode = N'EXPENSES',

            @FiscalYear_StartingDate = N'2012-04-01 00:00:00.000',

            @FiscalYear_EndingDate = N'2013-03-01 00:00:00.000',

            @TotalAmount = @TotalAmount OUTPUT

SELECT      @TotalAmount as N'@TotalAmount'

SELECT 'Return Value' = @return_value
