Column count duplicates

[RafaelCM]

Hello
I need to create a column that says how many times the information is repeated in a column.
For example, I have a table where each row represents a sale, and in each of these rows there is the name of the salesperson; I need to create a column in this table that says how many times the seller's name is repeated, without using groupings.

Seller	Date	Value	Count
Rafael	11/08/2022	100	3
José	11/08/2022	200	1
Zé	11/08/2022	300	1
João	11/08/2022	400	1
Zezinho	11/08/2022	500	1
Rafael	11/08/2022	600	3
Rafael	11/08/2022	700	3

Hi,

Create this calculated column formula

=calculate(countrows(Data),filter(Data,Data[seller]=earlier([seller])))

Hope this helps.

[RafaelCM]

thank you so much
however I have one more problem, in the dashboard I have a data filter, how do I make this formula obey the data filter? should I create a measure instead of a column? Does this formula also work if you are going to use it in a measure?

This formula's result will not update based on a slicer selection - only measures do.  Why should the count change based on a date slicer selection.  Share some data and show the expected result.

Hi

Option 1: create an Summarize Table, use CountX funtion, then Look up back

Option 2:

create measure

        name_seller = SELECTEDVALUE (Seller column)

create column

        count =

              var  a =  measure name_seller

              return COUNTX ( FILTER (table, Seller column = a), Seller column )
