    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

Got this error now.
A single value for column 'TagId' in table 'Events' cannot be determined....

I do not have any filters active in my filter fields.

 

Measure 3 =
var domain=SELECTEDVALUE('Events'[MachineId])
var max_date__=calculate(max('Events'[EventRaised]);FILTER(ALL('Events');'Events'[MachineId]=domain))
return
CALCULATE(MAX('Events'[TagId];FILTER(ALL('Events');'Events'[MachineId]=domain && 'Events'[EventRaised]=max_date__)))

Hi lukasjar 

 

you have not closed bracket after tagid in return section.

Calculate(max(table[tagid]),filter())

      What do you mean by not returning anything?

      In one your screenshot you are getting output.

      Thanks

        Yes that screenshot is from the code written by amitchandak pasted below.
        Now this code returns on 6 of the 11 MachineId I have. I do not understand why it dosnt send anything on the other ones as it has a TagId. The measure you pasted does not work for me. Can it have something to do with my date having date + timestamp? I am looking for the last timestamp. In query editor I have filtered down the data to just include the last day.

        LNBV = calculate(max(Events[TagId]);filter(Events;Events[EventRaised] = lastnonblankvalue(Events[MachineId];Events[EventRaised])))
