Advanced Date Filtering using DAX

[AleksandrMe]

Good day, 

I have data quesry consists of number of Execel files. 

Query has colunms "SHIP NAME" and "Date of Reports". Some of the "SHIP NAME" repeats various times with different "DATES". While ago I was interested to filter out only latest date lines for visuals and used following measures and custom colums:

1) Max Date = calculate(max('RNA Date of Report'[Date of Report].[Date]), filter('RNA Date of Report', 'RNA Date of Report'[Ships Name]=EARLIER('RNA Date of Report'[Ships Name])))

2) IsLatest = If('RNA Date of Report'[Date of Report].[Date]='RNA Date of Report'[Max Date].[Date],"Latest Audit", "All Audits")

Since there are much more lines in the quesry for the same "SHIPS NAME" - I'm looking for possibility to create filter for previous to last date. Some have 2 lines, but some have 3+ (dates). Any ideas? 

Thanks

Hi @AleksandrMe 

Can you add a sample of your data and result here?

For the Max Date measure, you can use LASTDATE ('RNA Date of Report'[Date of Report])
Max Date=LASTDATE ('RNA Date of Report'[Date of Report])

and then if you want to use that in the other measure, you can add a variable in your measure like this:

IsLatest =
VAR _MaxDate =
    CALCULATE (
        LASTDATE ( 'RNA Date of Report'[Date of Report] ),
        ALLEXCEPT ( 'RNA Date of Report', 'RNA Date of Report'[Ships Name] )
    )
RETURN
    IF (
        'RNA Date of Report'[Date of Report] = _MaxDate,
        "Latest Audit",
        "All Audits"
    )

Good day, 

Thnaks for reply. What I'm looking for is the new measure which will filter out date previous to last. The above one is not helping me, or I;m doing something wrong.

Raally looking for solution how to use DAX function to recognize LATEST, Previous Date for each line. 

I use below functions to recognize latest, but cannot progress more ("all audit"s need to be broken down on more conditions)

1) Max Date = calculate(max('RNA Date of Report'[Date of Report].[Date]), filter('RNA Date of Report', 'RNA Date of Report'[Ships Name]=EARLIER('RNA Date of Report'[Ships Name])))

2) IsLatest = If('RNA Date of Report'[Date of Report].[Date]='RNA Date of Report'[Max Date].[Date],"Latest Audit", "All Audits")

Any more ideas? 

THnaks
