Calculate Min/max column (Dax)

[Saxon10]

Hi,

I have table and the table contains the following columns are item and country code.

Query1

The same item has two different country code are ADMK and DMK. If same item has two different country code then DMK is first concern and ADMK is second concern. I want unique code against each item within the table.

Data and Result:

item	country code	Result
123	ADMK	DMK
123	DMK	DMK
1234	ADMK	ADMK
456	DMK	DMK
81	DMK	DMK
456	ADMK	DMK
890	DMK	DMK
890	DMK	DMK
564	ADMK	DMK
564	DMK	DMK

Query 2:

I have different situation. 

I have a two tables are data and report in data table the following columns are item(item duplicated) and country code and report table item only(unique).

If same item has two different country code then DMK is first concern and ADMK is second concern.

I want unique item against the item in report table and if item does not exist then NA.

I am looking for New calculated column options without duplicaation columns.

@CNENFRNL,

How can I replicated the same thing in power bi.

in Excel I am applying the following formula =IFERROR(IF(COUNTIFS(A$3:A$12,D3,B$3:B$12,"DMK"),"DMK",INDEX($B:$B,MATCH($D3,$A:$A,0))),"NA") (inbetween two tables)

Hi @Saxon10 ,

Please try the following calculated columns:

Column = 
VAR DMK =
    CALCULATE (
        COUNTROWS ( DATA ),
        FILTER (
            DATA,
            DATA[item] = EARLIER ( DATA[item] )
                && DATA[country code] = "DMK"
        )
    )
RETURN
    IF ( DMK > 0, "DMK", [country code] )

Result = 
VAR code =
    CALCULATE (
        MAX ( DATA[Column] ),
        KEEPFILTERS ( DATA[item] = EARLIER ( REPORT[Item] ) )
    )
RETURN
    COALESCE ( code, "NA" )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

Winth in table:

=IF(COUNTIFS($A$3:$A$12,$A3,$B$3:$B$12,"DMK"),"DMK",$B3)

@CNENFRNL ,

thanks for your reply and your solution working well but I can't see the both table item columns reference in your formula? How do I know it's giving the correct result against the id? Is that possibile to add the both item columns reference in your formula or alternative way to achive the result inculding both table item columns reference?

I want the same result within the table. How can I get it? I am try to copy the same formula in data table but it's not working. can you assit me.
