Column with count of email adress connected to serial number

Koliberus — Tue, 11 Oct 2022 13:19:24 GMT

Hello everyone,

Got problem with adding column that shows count of email adresses connected to serial number.
I have to seperated data sets (lets call them set A and B - both have "Serial Number" and "Email Adress" columns - relation is setted on "Serial Number"
I'm trying to get "valid check" columns between both.

I created separate Main Table in with:
- First column pull out with DISTINCT Serial Numbers from A Data;

- Second column COUNT number of B Data Serial Numbers in A Data based on first column;

- Third column check number of duplicated Serial Numbers in A Data;

- Fourth column does TRUE FALSE check for count of Serial Numbers in second and third count;

Now i need to create two separate columns that will show count of email adresses connected to serial numbers one from A and second from B Data in Main Table.

Aaaand... i'm stuck with that 😞

Thank You for taking interest in my problem 🙂

I'm attaching pbix example.

My data sources are Tale A and Table B

I created Valid Check Table like this:

Formulas i used in this Table for specific columns are:

1. Serial Number = DISTINCT('Table A'[Serial Number])

2. Table B SN Count =

COUNTROWS (

FILTER (

'Table B',

'Table B'[Serial Number] = EARLIER ( [Serial Number] )

)

) +0

3. Table A SN Count =

COUNTROWS (

FILTER (

'Table A',

'Table A'[Serial Number] = EARLIER ( [Serial Number] )

)

) +0

4. Valid SN = if('Valid Check'[Table A SN Count]=1 && 'Valid Check'[Table B SN Count]=1, 1, 0)

What i need now is to create three new columns in Valid Check Table:
- Count of emails for each Serial Number from Table A
- Count of emails for each Serial Number from Table B

- true/false if emails counts for specific Serial Number from both Tables are the same or not
