Table or Matrix with each month showing last 12 month of unique ID

[Anonymous]

Hi 

Is it possible to have a table of matrix that shows for each month the # of unique Cutomer ID for the last 12 months within each month. Example Jan-2021 value would show the # of unique customer ID over the last 12 calender month.

Thanks

Hi @Anonymous ,

Did you have a calendar table. You need to build one and create an one to many relationship between it and your fact table.

Then you can use the following measure:

Measure =
VAR CURRENTDATE =
    MAX ( Date[Date] )
RETURN
    CALCULATE (
        DISTINCTCOUNT ( Sales[CustomerID] ),
        DATESINPERIOD ( 'Date'[Date], CURRENTDATE, -1, YEAR ),
        ALL ( Date )
    )
