Measure Repeat Customer by Date

Hi all,

 

I think I have a somewhat easy question, but I'm having a hard time solving. I'm try to find the count of repeat customers by year, comparing this year to the previous year. For example, in the sample data table John would not count as a repeat customer because it was not in consecutive years. Thank you in advance!

 

Sample Data

YearCustomer
1/1/2018| John
1/1/2018| Sam
1/1/2019| Sam
1/1/2019| Leon
1/1/2020| John
1/1/2020| Sam
1/1/2020| Leon

 

 

Expected Result

 

YearRepeat Customer from Previous Year
1/1/2018| 0
1/1/2019| 1
1/1/2020| 2

    Hi Index_Match 

     

    Try this measure [without Date Table]:

    Repeat Customers =
VAR _A =
    ADDCOLUMNS (
        Customer,
        "CY",
            CALCULATE (
                DISTINCTCOUNT ( Customer[Customer] ),
                FILTER (
                    ALL ( customer ),
                    YEAR ( Customer[Year] )
                        = YEAR ( EARLIER ( Customer[Year] ) ) - 1
                        && Customer[Customer] = EARLIER ( Customer[Customer] )
                )
            ) + 0
    )
RETURN
    SUMX ( _A, [CY] )

     

     

    output:

    Index_Match solution attached, and core measure is this:

     

    Repeat Customers = 
VAR __thisYearCustomer = VALUES ( Customer[Customer] )
VAR __lastYearCustomer = CALCULATETABLE ( VALUES ( Customer[Customer] ), PREVIOUSYEAR ('Calendar'[Date] ) ) 
RETURN
COUNTROWS ( INTERSECT ( __thisYearCustomer, __lastYearCustomer ) ) + 0

      How would the measure need to be adjusted if using a date table?
