    Hi asjones，

     

    Since you need 2 columns based on the max date,I would suggest you first create a column to get the max date,using below M codes:

    =Table.Max(#"Changed Type","Date")

    Then create another 2 columns to get 7days and 14days:

    =if [Date]>Date.AddDays([Max date.Date],-7) then "7 days" else null
    =if [Date]>Date.AddDays([Max date.Date],-14) then "14 days" else null

    And you will see:

    For the related .pbix file,pls see attached.

     

    Best Regards,
    Kelly

v-kelly-msftthanks for the reply... that is probably the cleanest option and it should also work cleanly in Excel Power Query also.

 

thanks
