Calculate difference between cards in fully responsive report

[RFC_JWK]

Good afternoon, 

I am trying to insert a card that calculates the difference between two existing cards. The report that I would like to show makes it possible to show the sales of four different years, which can be handpicked using a slicer. This allows users to compare the years they would like to see. 

To make it a bit more concrete, let's say I would like to compare the bike sales of various years (and these years can be handpicked by the user, which is why the report should be responsive in case one selects a different year). 

By selecting the year 2015, the cards below will show the amount of bikes sold and the sales revenue. The page basically looks like this:

Year (slicer) - 2015	Year (slicer) - 2016	Year (slicer) - 2017	Year (slicer) - 2018
Sales volume 2015: 80 bikes	Sales volume 2016: 90 bikes	Sales volume 2017: 50 bikes	Sales volume 2018: 70 bikes
Sales revenue 2015: € 16,000	Sales revenue 2016: € 18,000	Sales revenue 2017: € 10,000	Sales revenue 2018: € 14,000

I would like to include cards in between these existing cards that calculate the difference between the selected years, meaning the report should look like this:

Year - 2015		Year - 2016		Year - 2017		Year - 2018
SV: 80	+10	SV: 90	-40	SV: 50	+20	SV: 70
SR: 16k	+2k	SR: 18k	-8k	SR: 10k	+4k	SR: 14k

In the future, I would also like to include multiplications using these numbers, but this is the first step towards that. Is this possible? Can anyone point me in the right direction? 

Thanks in advance! 

Best regards, Jan

Hi @v-lionel-msft, 

Thank you for your message. This works as long as the order does not change, but not when trying to compare two non-subsequent years, which is how the data should be presented in my case. Do you know if this is possible?

Best regards,

Jan

Hi @RFC_JWK ,

For example, if you want to compare the sales value of 2015 and 2017, you can change the parameter in this formula to 2。

Hi Lionel,

Unfortunately it has not yet been solved. This would require the user to manually change the formula when selecting different years for the comparison.

Hi @RFC_JWK ,

You can create a 'What if' parameter  and modify the [Measure2].

Measure 2 = 
CALCULATE(
    SUM(Sheet7[Sales]),
    FILTER(
        ALLSELECTED(Sheet7),
        Sheet7[Column] = MAX(Sheet7[Column]) && Sheet7[Year] = MAX(Sheet7[Year]) + [Parameter Value]
    )
)

Please refer to my .pbix file.
