last year month figure display in current month

[gzboy008]

Hi forum, I'm in a deep puzzle.

Hope someone can lend me a hand. Thanks in advance!

Here's the story. I have the testing data as below.

When I press apply filter button. it will set the filtering to retrieve data from 1/1/2014 ~ 2/15/2014.

How can I retrieve the last year figure and display at the same line.

Below's what I expected.

Hey,

Here's something that might work for you.

I've used a little trick in the generation of the calendar that allows you to calculate previous year figures in the same rows as current year figures. Please note that you will need to use set analysis in every expression if you decide to utilize this method.

Hope this helps

Hi Kelvin

Allright then i think Teemu's approach is the correct one. You need to have flags for current and previous year and use sat analysis in your formula.

Didn't know that only months is not sufficient.

Kind regards,

Hi --,

I don't want to display 2013 data. Anyway, thanks!

I need to have year & month. Sorry I have little idea about your talking

Hi Teemu,

The table has more than 10 million records, use current/past flag will increase the data amount to double. Are there any other approach? Like "above" or somthing?

Does anybody know are there any approaches something like "above" can retrieve last year figure and show them in the same row of current month? Add current/last year flag will increase the data volumn to double.

Thanks!

Hi,

The amount of rows should not change since the calendar table is separated from the fact data. It should only have as many rows as there are dates between the min and max dates of your data set, multiplied by 2.

edit: if you take a look at the amount of rows in the fact table of your Test application, it still has only 8 rows, just as you've defined in the load even if there are current/previous flags in the calendar table.
