Dynamic Difference Measure Using Slicer

Hi All,

 

I have the following data structure (about 15 other data columns not shown here):

CoCodePeriodPTBI
Ent12016 YE100000
Ent12017 YE117558
Ent12018 Q1125469
Ent22016 YE449514
Ent22017 YE283007
Ent22018 Q1466238


What we want to do is take the dynamic difference in PTBI for the periods selected by the slicer, see example below. Any thoughts on how to accomplish this? Our goal would be to keep it pretty dynamic so that as we add periods to the dataset, we can change the comparisons.

 

For example, the matrix would look like this:

CoCode2016 YE2017 YEDifference
Ent1         100,000         117,558        17,558
Ent2         449,514         283,007    (166,507)

 

 

I'm currently using the following DAX expression, but it's too static because it forces you to put in the columns that we want to compare, and it doesn't work well in a matrix because it flips the values on the earlier period's column.

 

Difference =
IF(
HASONEVALUE('Dataset'[Total Total Pre-Tax Book Income]),
BLANK(),
CALCULATE(
SUM('Dataset'[Total Total Pre-Tax Book Income]),
FILTER('Dataset','Dataset'[Period] = "YE 2017")
)
- CALCULATE(
SUM('Dataset'[Total Total Pre-Tax Book Income]),
FILTER('Dataset','Dataset'[Period] = "YE 2016")
)
)

 

Thanks!

@Anonymous,

 

You may add the following measure.

Measure =
VAR p1 =
    MIN ( 'Dataset'[Period] )
VAR p2 =
    MAX ( 'Dataset'[Period] )
RETURN
    IF (
        ISINSCOPE ( 'Dataset'[Period] ),
        SUM ( 'Dataset'[PTBI] ),
        CALCULATE ( SUM ( 'Dataset'[PTBI] ), 'Dataset'[Period] = p2 )
            - CALCULATE ( SUM ( 'Dataset'[PTBI] ), 'Dataset'[Period] = p1 )
    )

Sam,

 

It turns out that that doesn't work quite as well as I originally thought... If a value isn't present for one of the periods, it says there's no difference, but still (correctly) includes the difference in the total, which seems odd.  Also of note: I converted the periods to dates, so they read 12/31/2016, 03/31/2017, etc..

 

I've pasted a table of what it's doing, and what I'd expect it to do below. Any help you can provide would be greatly appreciated. Thanks!

@Anonymous do you want that user will select one period in slicer and then measure will look at the previous period and give the difference? 

 

or you want use to select two period and then give the difference between those two period?

@parry2k I'd like the user to select the two periods in one slicer, or if it's easier, two slicers to compare the two periods.
