How to build power Bi Count If Formula such as this excel formula IF(COUNTIF(P$3:P3,P3)=1,1,"")

[Ahmed_Mohamed]

The idea is to remove any duplicate value and replaced by blank and then count it once for example 

if I have 

Raw 1               Product A

Raw 2              Product A

Raw 3              Product A 

All three product in three rows I need to count 1 record and leave the other two as blank to be like this 

Raw 1              Product A      =   1             

Raw 2              Product A      = blank

Raw 3              Product A     = blank 

Thanks and I waiting for someone to help me ...thnx a lot

Hi @Ahmed_Mohamed 

You may get it in query editor as below.Please paste below formula in advanced editor to check the steps.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCijKTylNLlFwVIrVIY7nhJ8XCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Column1"}, {{"Partition", each Table.AddIndexColumn(_, "Index",1,1), type table}}),
    #"Expanded Partition" = Table.ExpandTableColumn(#"Grouped Rows", "Partition", {"Index"}, {"Partition.Index"}),
    #"Added Conditional Column" = Table.AddColumn(#"Expanded Partition", "Custom", each if [Partition.Index] = 1 then 1 else null)
in
    #"Added Conditional Column"

Hi @v-cherch-msft 

Thanks a lot for the solution by using advancer editor, but the issue in my data that I'm using a data table and I do not have permission to access the edit query as we are using SQL server datasets, so the only solution that I have to use DAX formula giving the same purpose

Is DAX formula applicable to my logical MS excel formula?

Thanks again

Hi @Ahmed_Mohamed 

I would suggest you add an index column in sql server for the table.Then create below two columns.

Column =
CALCULATE (
    COUNT ( 'Table1'[Column1] ),
    FILTER (
        'Table1',
        'Table1'[Column1] = EARLIER ( 'Table1'[Column1] )
            && 'Table1'[Index] <= EARLIER ( 'Table1'[Index] )
    )
)

Column 2 = IF(Table1[Column]=1,1,BLANK())

Hello @Ahmed_Mohamed 

The challenge is that in PowerBI "cell" C2 (the one with the second formula) has no idea what is in any of the other cells. 

In your data, what is making the Product appear multiple times?  What is different on row 2 and 3?  We might be able to use that information along with IF and DISTINCTCOUNT to get what you need.

Hello jdbuchanan71, 

Referring to your point@ the different in Raw 2 and Raw 3 is another needed data columns and is not duplicated for example product A includes 3 different SKUs, 3 different number of Orders, erc.. so I need to say I have 1 product include multiple items 

[jdbuchanan71]

@Ahmed_Mohamed If you use DISTINCTCOUNT ( table[Product] ) it will give you the correct values, even at the total level.  It won't hide the value on the additional rows but may get you close to what you are looking for and will work regardless of the additional columns in your visual.
