    Hi markpendlebury

     

    I think this calculated table might be getting close.  Just replace my Table2 with the name of your table

     

    Table 3 = SELECTCOLUMNS(
            FILTER(
                CROSSJOIN(
                    SELECTCOLUMNS( 
                        SUMMARIZECOLUMNS(
                            'Table2'[Email],
                            "MAX ID",
                            MAX('Table2'[ID])
                            ),
                            "MAX Email",[Email],
                            "MAX ID",[MAX ID]
                          ) ,
            'Table2'
            ),
            'Table2'[Email]=[MAX Email] && 
            Table2[ID] = [MAX ID]
            ),
            "ID",[ID],
            "Email" , [MAX Email]

Phil_Seamark Thanks for this answer. I thought I might need to create this as a Table and this appears to work perfectly.

I did need to add my additional fields but that was pretty simple. Thanks

 

My original source table was 200,000 rows so I've had to restrict the incoming dataset (which is ok) as the refresh was timing out the Power BI Gateway but I think I've got that working now.

 

Thanks
