How can I see which clients have bought a specific product in only one of last three months?

Hi!

I'm having trouble in figuring out how can i create a measure that gives me which clients have bought a specific product in only one of the last three months.

For an example: If the months in consideration are: january, february and march, I want clients that have bought in jan but not in feb and march, or clients that have bought in feb, but not in jan and mar or even clients that have bought in mar but not in jan and feb.
I know how to do it for a specific month, as in:

CALCULATE (
[#Sales],
Product[Product Name] = "XXX",
Period[Month/Year] = "jan/2022"
)

Then, i manually create a table where the first column is the clients ID and the second column is the measure above. I wanted a measure that gave me which clients bought the product in only one of the last 3 months.

hi @felipescamilo 

try like:

CALCULATE (

[#Sales],

Product[Product Name] = "XXX",

Period[Month/Year] in { "feb/2022", "jan/2022", "mar/2022"}

)

hey @FreemanZ , thanks for your answer. But in this case i would get a list of all clients that bought in those 3 months. What i want are clients that bought in only one of the three months.

hi @felipescamilo 

try like:

CALCULATE (
    [#Sales],
    Product[Product Name] = "XXX",
    (
        Period[Month/Year] = "jan/2022" 
            && Period[Month/Year] <>"feb/2022" 
            &&Period[Month/Year] <>"mar/2022"
    )
    || 
    (
    	Period[Month/Year] = "feb/2022" 
    		&& Period[Month/Year] <>"jan/2022" 
    		&&Period[Month/Year] <>"mar/2022"
    )
    || 
    (
    	Period[Month/Year] = "mar/2022" 
    		&& Period[Month/Year] <>"feb/2022" 
    		&&Period[Month/Year] <>"jan/2022"
    )
)

@FreemanZ the thing is I need to see clients that bought in only one of the last three months. For example: if he bought in jan, I need the number of sales in february and march to be = 0.
I'm thinking about something like this, but easier:

IF (
AND (
CALCULATE (
    [#Sales],
    Product[Product Name] = "XXX",
    Period[Month/Year] = "feb/2022" 
    )=0,
CALCULATE (
 [#Sales],
    Product[Product Name] = "XXX",
    Period[Month/Year] = "mar/2022" 
    )=0,
CALCULATE (
[#Sales],
Product[Product Name] = "XXX",
Period[Month/Year] = "jan/2022" 
)
))
