Last Three months sales?

[#1]

Dear Community,

i trying to calculate last three months sales based on the selection.

suppose if i select Jan-2013 than i need to show the sales for last 3 months. (i,e: dec-2012 ,Nov-2012, Oct-2012).

but the main concern is based on  financial year which starts from April-May.

if i select 2012-Apr than last 3 months 2011-Mar ,2011-Feb ,2011-jan.

i have attached the qvw file , which contain financial year and financialMonth number and FQuarter.

hope someone will help me.

Thanks,

mukram.

Hi Mukram,

When I have this kind of filter to do, I use counter in my calendar table.

So, in your case, you can add in the Sales table such a column:

(year(today())*12+num(month(today())))-(year(TransactionDate)*12+num(month(TransactionDate))) as MonthCounter

Then, in your chart, you can use a set analysis like this:

=sum({$<MonthCounter={'<=$(=max(MonthCounter))>=$(=max(MonthCounter)-2)'}>}[Sales VAL])

Vincent
