Filtering data before calculation

Hi all.

asimpleman9to5_0-1660531019481.png

From the screenshot shown above, I would like to filter the serial number first before proceeding to calculate the difference in the higest and lowest voltage within each serial number. Is there a possible way in achieving the above mentioned outcome? Relatively new to power BI so I am quite unsure with how to approach this problem. Any help would be greatly appreciated.

Hi,

I assume you want to create a calculated column.

Please check the below picture and the attached pbix file.

Diff calculated column =
MAXX (
    FILTER ( Data, Data[Serial No] = EARLIER ( Data[Serial No] ) ),
    Data[Voltage]
)
    - MINX (
        FILTER ( Data, Data[Serial No] = EARLIER ( Data[Serial No] ) ),
        Data[Voltage]
    )
