Qlikview: Past Year data calculations - qlikview

Question

I have a scenario.
In the sample table below, I need to show the sales by year…
And for each year, I need to show the last yr and last 2nd year sales for that year.
For example in 2014,
Current Year = 2014 Sales
Last Year = 2013 Sales
Current Year = 2013 Sales
Last Year = 2012 Sales
|----------2013------------|---------2014-------------|
| Last Year | Current Year | Last Year | Current Year |
Ive tried but when i nest them under a year dimension.. the calculations are not working.. is there a way around this, to come up with this kind of report format? our user is very particular in having such format..
many thanks for the help.

Answer 1

I'd simply hardcode all rows, and skip the year dimension:
Current Year
Sum({< Date = {">=$(=YearStart(min(Date),0"}*{">=$(=Addyears(max(Date),0)"} >} SalesAmount)
Last Year:
Sum({< Date = {">=$(=YearStart(min(Date),-1"}*{">=$(=Addyears(max(Date),-1)"} >} SalesAmount)
-2 Year:
Sum({< Date = {">=$(=YearStart(min(Date),-2"}*{">=$(=Addyears(max(Date),-2)"} >} SalesAmount)

I think this could be achieved using a pivot table. Here's an example.

You can solve this problem at the script side while loading data. So that you can compare year to date data with previous year with until corresponding month.
Transaction_Table:
LOAD date,productID,amount
FROM data.qvd;
concatenate
Load AddYears(date,1) as date,productID,amount_1
from data.qvd where date<=AddYears($(=max(date)),-1);
Data_Table:
load distinct
date,
month(date) as Month,
year(date) as Year
resident Transaction_Table;
There will be two coloumns "amount" is current date's data and "amount_1" is previous year's same day data.
Create pivot chart put year to top and product to left and create two expressions. One for calculation of amount_1: previous term and one for amount: current term
You can name expressions:
previous year label: =year-1
current year label: =year
