Hi,
I have 2 data tables and each of them have in common a column with a unique code for each row, "customer ID"
I linked the 2 tables using the common unique value "customer ID"
My objective is to count which and how many of each unique code "customer ID" in [Table 1] are existing in [Table 2] , and to return zero count if the unique value doesn't exist at all in [Table 2]
I've read and watched alot of explinations but non of them to work out for me

Hi @MhdMur ,
Based on your description, and based on my understanding, if there are duplicate values in Table II, I'm not quite sure if you need to count all Table I values that appear in Table II, or just how many unique Table I values appear in Table II i.e. de-duplicated. You can try the following two methods.
Here are my test data:
1. Calculate contains duplicate values
Count of Customer ID in Table 1 =
COUNTROWS(
FILTER(
'Table1',
NOT(ISBLANK('Table1'[Table1 customer ID]))
&&
CALCULATE(
COUNTROWS('Table2'),
FILTER(
'Table2',
'Table2'[Table2 customer ID] = 'Table2'[Table2 customer ID]
)
) > 0
)
)
2. Calculate without duplicates
Count = COUNTROWS(
FILTER(
'Table1',
NOT(ISBLANK(
LOOKUPVALUE(
'Table2'[Table2 customer ID],
'Table2'[Table2 customer ID],
'Table1'[Table1 customer ID]
)
)
)
)
)

Hi, create a table visual,
first columumn is Customer ID from table 1
second dolumn is a measure = count(customer id from table 2) +0
There you go.
Kudos and mark as solution appreciated.
