DAX measure value not repeated in a table cell if it's already shown in the previous row

[teresating886]

Hi, The DAX measure I want to improve is tractor count. It counts distinct tractor numbers.

Tractor # = CALCULATE(DISTINCTCOUNT('Table'[ivh_tractor]), GROUPBY('Table','Table'[ivh_driver]))

What I want to achieve is that the "1"s highlighted in the table should be blank because they have been countetd in the previous rows. Here is the sample dataset. Thank you for your input.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [delivery_date = _t, ivh_driver = _t, ivh_invoicenumber = _t, ivh_tractor = _t])

Hi @teresating886 ,

Try this.

Tractor # = 
COUNTROWS(
    FILTER(
        'Table',
        'Table'[ivh_invoicenumber]=CALCULATE(MIN('Table'[ivh_invoicenumber]),ALLEXCEPT('Table','Table'[ivh_driver]))
    )
)

@teresating886 ,

Did you created any measure or is it a direct column that you are using in visual?

Thanks,
