Hi, I am farily new to Dax and I need to replicate in Power BI this formula I have on Excel. I need to create a calculated in Power Bi that  will look for how many times a number appears on a Column name DEL Delivery Reference and if it appears 1 time, the result should be 1 in the calculated column, if it appears 2 times, the result should 0.5 (1/2), if it appears 3 times the resul should be 0,3333 (1/3), and so on. 

Any help would be deeply appreciated.

Hi,

I am not sure how your semantic model looks like, but I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file whether it suits your inquiry.

Calculated column expected result =
DIVIDE (
    1,
    COUNTROWS (
        FILTER (
            Data,
            Data[DEL Delivery reference] = EARLIER ( Data[DEL Delivery reference] )
        )
    )
)
