Generate MaxDate within a group

I have a table full of test instances. Each test is performed against multiple models by multiple individuals, sometimes multiple times within the same day.


I want to retrieve the results for each unique User/Model/Test within a calendar week only for the very last occurence within that week


On my table I have a numeric datekey, which includes the time. I have also including grouping columns for Year+Week (based on the date time stamp) and an item key combo of User/Model/Test


I am getting a "expression refers to multiple columns...cannot be converted to a scalar value" error with the following formula:


Column = GROUPBY(table,table[Uniquename],table[WeekGroup],"MaxDate",MAXX(CURRENTGROUP(),table[datekey]))


Not sure if I need an additional table of unique values or if I'm missing something else
