    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

measure is automatically filtering for those rows only which are in filter context with non blank values.

 

Measure 3 =
var domain=SELECTEDVALUE('Table'[Domain])
var max_date__=calculate(max('Table'[date]),FILTER(ALL('Table'),'Table'[Domain]=domain))
return
CALCULATE(MAX('Table'[Status]),FILTER(all('Table'),'Table'[Domain]=domain && 'Table'[Date]=max_date__))
 
i have modified return section and added  "all", this will return all table rows.

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
