One to Many Relationship

Hi Comunity,

 

Apologize if this has been discussed earlier, I could not find a thread.

 

I have 2 tables (mockup data):

Table 1

Product ID
P1
P2
P3
P4

 

Table 2

Product IDMfg Year
P22020
P22019
P32021

 

How can I count the number of Product IDs that do not have a Mfg Year in Table 2 - in this case would be 2 (P1, P4)?

 

Thank you in advance!

= COUNTROWS( FILTER( 'Table 1', ISEMPTY( CALCULATETABLE( 'Table 2' ) ) ) )

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!
