How to sort by Total Sum calculated field in a Tablix

Question

I have a Report in Microsoft Visual Studio 2010 that has a tablix. I have a list of Customers Sales grouped by Month. I would like to add a grand total of all the Months for each customer. I would then like to sort by descending amount of the grand total. I have added the grand total, but I can't figure out how to sort on it. Any suggestions?

Here is the initial dataset query:

SELECT
Customer, CustomerName, FiscalMonthNum, FiscalYear, SalesDlr
FROM
CustomerSalesDollars
WHERE
FiscalYear IN ('2013')
ORDER BY
SalesDlr DESC

Answer 1

with CSD as (
    select Customer, CustomerName, FiscalMonthNum, FiscalYear, SalesDlr
    from CustomerSalesDollars
    WHERE FiscalYear in ('2013')
), YearlyTotals as (
    select FiscalYear, Customer, CustomerName, SUM(SalesDlr) as YearlyTotal
    from CSD
    group by FiscalYear, Customer, CustomerName
)

select * from YearlyTotals
order by YearlyTotal desc

If you still want all the monthly breakdowns:

with CSD as (
    select Customer, CustomerName, FiscalMonthNum, FiscalYear, SalesDlr
    from CustomerSalesDollars
    WHERE FiscalYear in ('2013')
), YearlyTotals as (
    select FiscalYear, Customer, CustomerName, SUM(SalesDlr) as YearlyTotal
    from CSD
    group by FiscalYear, Customer, CustomerName
)

select CSD.*, YT.YearlyTotal from YearlyTotals YT
join CSD on CSD.FiscalYear = YT.FiscalYear
and CSD.Customer = YT.Customer
and CSD.CustomerName = YT.CustomerName
order by YearlyTotal desc, CSD.SalesDlr desc
