    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]
)

Perfect, thank you.  😁  DAX is a much better way of course! 🙄

 

Ok, so next problem (sorry!).  I actually need to expose the MAX(Last Booking Date) across all Customer entities associated with the Parent Customer.  If I create a measure using Last Booking Date = MAX ( Table[Booking Date] ) then I get the Last Booking Date for the individual Customer in my report - which is at Customer Level.

 

This is what I'm after, i.e. the Parent Last Booking date is the MAX of all Booking Dates associated with child Customer entities.

Thanks!

Hi, Anonymous 

 

So what should be the correct result?

Can you share some sample data? So we can modify the code according to the field.
