    Hi Anonymous 

     

    That's why I asked you to share sample data...Your previous sample is incomplete.

    Try this:

    Last Booking Date =
MAXX (
    FILTER (
        ALL ( table ),
        [Parent Cust ID] = SELECTEDVALUE ( table[Parent Cust ID] )
    ),
    [Booking Date]
)

Hi v-janeyg-msft ,

 

Sorry, I'm not sure I understand.  The column you've highlghted in this sample table is the expected result.

 

Both rows have the same Parent Cust ID, but differing Cust Last Booked Date.  The Parent Last Booking Date is displaying the MAX Cust Last Booking Date across all child entities.

 

Naturally, this value will be repeated or all rows with the same Parent Cust ID, but this is not a problem.

 

Hope that clarifies?
