count common value for columns and rows

[Aida_Ken]

Hi everyone, 

After hours of arguing with ChatGpt, sudden blurry vision and probably acute OCD due to errors showing up with my formula, Im finaly here. 

All I want is to display the count of products with the same DCI for each combination of labs, even if the labs are different ( all what I managed to do is to display it only when the lab is the same, if my boss sees it ... 😏)

Well that's it, Im counting on any charitable soul here, thanks in advance 🙏🏻

PS: the actual formula:

CommonProducts =
CALCULATE(
COUNTROWS(db),
ALLEXCEPT(db, db[Lab], db[DCI])
)

Hi  @Aida_Ken ,

I created some data:

Here are the steps you can follow：

1. Create calculated table.

Table =
var _table1=
DISTINCT('db'[Lab])
var _table2=
DISTINCT('db'[Lab - Copy])
return
CROSSJOIN(
    _table1,_table2)

2. Create calculated column.

Column =
COUNTX(
    FILTER(ALL('db'),
    'db'[Lab]=EARLIER('Table'[Lab])),[the actual formula:CommonProducts])

3. Result:
