FIlter Conect > Measure that calculates delta based on filter

[Anonymous]

Hi,

I have a question that feels very simple but I just can't work it out.

My data table looks a little like this:

Country	ProductCategory	Location	Quantity	Cost
Italy	Helmet	In Store	6	22
Germany	Gloves	In Store	8	50
France	Gloves	In Store	2	21
Spain	Shirt	In Store	9	25
Italy	Helmet	Road Show	6	22
Germany	Shirt	Road Show	9	44
France	Helmet	Road Show	4	25
Spain	Helmet	Road Show	2	27
Italy	Shirt	In Store	7	35
Germany	Helmet	In Store	6	45
France	Helmet	In Store	10	41

I've created a measure that calculates the cost per product via CostPerProduct =

DIVIDE(
    SUM(Cost),
    SUM(Quantity),
    0
)

What I want to do is create a measure that calculates the difference between the CostPerProduct for "In-Store" and "Road Show" locations. I thought the following measure would help me with this:

CostPerProductDelta =

CALCULATE(
   DIVIDE(
      SUM(Cost),
      SUM(Quantity),
      0
   ),
   Table[Location]="In-Store",
   ALL(Table[Location])
) - 
CALCULATE(
   DIVIDE(
      SUM(Cost),
      SUM(Quantity),
      0
   ),
   Table[Location]="Road Show",
   ALL(Table[Location])
)

Now, I would assume htat this would show me the difference between the CostPerProduct for In-Store and Road Show locations. Unfortunately, it sometimes shows a '-Infinity' value for CostPerProductDelta when I set a page level filter to 'In-Store'.

What am I missing here?

Hi @Anonymous 

If you want to calculate the cost per product per country,

please create measures as below

In Store = CALCULATE(SUM(Table1[Cost])/SUM(Table1[Quantity]),FILTER(ALLEXCEPT(Table1,Table1[Country],Table1[ProductCategory]),Table1[Location]="In Store"))

Road Show = CALCULATE(SUM(Table1[Cost])/SUM(Table1[Quantity]),FILTER(ALLEXCEPT(Table1,Table1[Country],Table1[ProductCategory]),Table1[Location]="Road Show"))

difference = [In Store]-[Road Show]

For some line, there is no data for these two measures, to see these, you need to click on any column from the table and enable "show data with no data".

Hi Maggie (@v-juanli-msft),

Thanks for your elaborate answer. This really helps a lot.

I hope you can find the time to take a look at one other small question regarding your response.

In the future we will probably increase the number of dimensions in the dataset. I don't really want to add all dimensions except 'Location' to the ALLEXCEPT function. Is it safe to assume that the following formula works as well:

In Store = CALCULATE(SUM(Table1[Cost])/SUM(Table1[Quantity]),FILTER(ALL(Table1[Location]),Table1[Location]="In Store"))

? It appears to yield the same result now, but I'm not sure if this will still be the case when we add dimensions.

Thanks in advance!
