Current Month and Previous Month

[#1]

Hi All,

I need to take current and previous month sales based on the selected month and year

My Sales Month  looks like this 1,2,3,4,5,6,7,8,9,10,11,12

My Sales Yerar looks like this 2011,2012,2013

To calculate current month sales i used this expression below (based on selected month),

=

sum({<SALES_MONTH={"$(=max(SALES_MONTH))"}>} $(vSales)

It works but when i try to calculate the previous month using the expression below, value is coming as "0"

=

sum({<SALES_MONTH={"$(=max(SALES_MONTH)-1)"}>} $(vSales)

Kindly guide where i'm wrong in this expression

Thanks,

Selva

for current--

sum({<SalesMonth={"$(=(SalesMonth))"},SalesYear={"$(=(SalesYear))"}>}Sales)

for previous--

sum({<SalesMonth={"$(=(SalesMonth)-1)"},SalesYear={"$(=(SalesYear))"}>}Sales)

Hi Selva,

Your expresion look fine. Can you tell me the definition of $(vSales)?

Create a numeric month field in the script: num(month(date#(MonthName,'MMM'))) as MonthNumber

You'll also need an incremental month field because the monthnum of Jan is 1 and the previous month is not 0, but 12 in the previous year. You can add a field like this: Year*12+num(month(date#(MonthName,'MMM'))) as PeriodNumber. You can then use the PeriodNumber field in the set analysis expressions:

Current: sum({<Sales_Year=,Sales_Month=,PeriodNumber={$(=max(PeriodNumber))>} Sales)

Previous Month: sum({<Sales_Year=,Sales_Month=,PeriodNumber={$(=max(PeriodNumber)-1)>} Sales)

Same Month previous year: sum({<Sales_Year=,Sales_Month=,PeriodNumber={$(=max(PeriodNumber)-12)>} Sales)

Dear Selva,

In that case, still you can make a DATE using your table fields.

Like Date(Date#('2012-Jan-01','YYYY-MMM-DD'),'DD/MM/YYYY')
