Calculate the most common cost

[dmytro_po]

Greetings,

please help to write a measure that calculates the most common cost for each product.

Try this:

First a measure to count rows.

NoRows = COUNTROWS(Data)

Then figure out the most common cost. The FIRSTNONBLANK deals with ties, without it you will get an error in the precense of the two (or more) cost values being most common.

MostCommonCost = 
FIRSTNONBLANK(
    TOPN(
        1, 
        VALUES(Data[Cost]), 
        RANKX(ALL(Data[Cost]),[NoRows],,ASC)
    ), 
    1
)

That should do it.

Sorry, but when I introduce the code, the equivalent for [NoRows] gets underlained in red and tells me that "Argument '3' in ALL function is required'. Which could be the error here?:

1. M.PST = 
FIRSTNONBLANK(
    TOPN(
        1;
        VALUES('Datos Numericos'[1.PST Compromiso]);
        RANKX(ALL('Datos Numericos'[1.PST Compromiso];[Nº Filas];;ASC)
     );
     1        
 )

Where [Nº Filas] = COUNTROWS('Datos Numericos')

@GuillemXII, you missed a closing parenthesis:
ALL('Datos Numericos'[1.PST Compromiso]

A silly mistake on my part... It works fine now! Thank you!

@GuillemXII, you missed a closing parenthesis:
ALL('Datos Numericos'[1.PST Compromiso]

@erik_tarnvik, great thanks. That helped me a lot.

Hi @dmytro_poUse this measure

CommonCost :=
CALCULATE (
    VALUES ( Table1[Cost] ),
    FILTER (
        Table1,
        MAXX ( Table1, CALCULATE ( COUNT ( Table1[Cost] ) ) )
            = CALCULATE ( COUNT ( Table1[Cost] ) )
    )
)

Greetings!

Could you please help to creare a measure, which would calculate the most comon cost for each product.

Thank you in advance for your help.

One way to do this:

For this Enter Data query:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCijKTylNLlEwVNJRMlWK1UEVMcMQMSdZxAgoYkKWiCmGiCGKiDFWESMMEWMMEVMi1GAViQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Product = _t, Cost = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Product", type text}, {"Cost", Int64.Type}})
in
    #"Changed Type"

You can create this measure:

Mode = IF(
   CALCULATE(
       MAXX(
          VALUES(ProductCosts[Cost]),
              CALCULATE(
                    COUNTROWS(ProductCosts)
              )
       ),
       ALLSELECTED(ProductCosts)
   )
   = COUNTROWS(ProductCosts),
   "MODE",
   BLANK()
 )
