GROUPBY and VLOOKUP (???)

[DenTOK]

Dear The Community World, seems I can not solve my task without your help!

I have a table and I need to make grouping (firts by Project, then MAX Rev.Date, then MAX Rev.Number) and afterwards return the value from another coloumn.

More clear in the picture bellow:

I didn't find a similar task in our Forum. 

Looking forward with your response!

Hi @DenTOK 

Try this:

Latest Code = 
IF (
    HASONEVALUE ( Projects[Project] ),
    CALCULATE ( 
        SELECTEDVALUE ( Projects[CODE] ),
        GENERATE ( 
            LASTDATE ( Projects[Revision Date] ),
            LASTNONBLANK ( Projects[Revision Number], 0 )
        )
    )
)

The key part of the measure is GENERATE ( ... ), which finds the maximum Revision Date using LASTDATE (returning a 1x1 a table), and then finds the maximum Revision Number in the context of that date filter using LASTNONBLANK (also returning a 1x1 table). These become a combined filter, and the single value of CODE is returned with this filter applied.

The measure is also restricted to return blank unless a single Project is visible in the filter context.

Regards,

Owen
