    share your pbix.

     

    and where are you adding this query

     

    select A.* from dbo.events a
    left join (select MachineID,max(EventRaised) _EVENT from dbo.[events]
    Group by MachineID) b ON A.MachineID=B.MachineID AND a.EventRaised=B._EVENT
    WHERE b._EVENT IS NOT NULL

     

    Get Data->Select Sql server -> ENter server name  & database name->DirectQuery Mode-> Click on advance -> paste this query there ->

    And load your data.

     

    this will give you direct result set

You can use a subquery. The subquery will get the Max(CompletedDate). You then take this value and join on your table again to retrieve the note associate with that date:

select ET1.TrainingID,
ET1.CompletedDate,
ET1.Notes
from HR_EmployeeTrainings ET1
inner join
(
select Max(CompletedDate) CompletedDate, TrainingID
from HR_EmployeeTrainings
--where AvantiRecID IS NULL OR AvantiRecID = @avantiRecID
group by TrainingID
) ET2
on ET1.TrainingID = ET2.TrainingID
and ET1.CompletedDate = ET2.CompletedDate
where ET1.AvantiRecID IS NULL OR ET1.AvantiRecID = @avantiRecID
