Difference (Items) between 2 tables

Hi Jagan_MFilterIT ,

Please create a new table:

Crossjoin Table = 
CROSSJOIN (
    VALUES ( 'Transaction Table'[Country] ),
    DISTINCT (
        UNION (
            VALUES ( 'Base Product List'[Product Name] ),
            VALUES ( 'Transaction Table'[Product Name] )
        )
    )
)

Then create measure and filter Measure = 1 for this visual.

Measure = 
var BaseTab = 
    CROSSJOIN (
        VALUES ( 'Transaction Table'[Country] ),
        VALUES ( 'Base Product List'[Product Name] )
    )
var TransTab = 
    GROUPBY ( 
        'Transaction Table',
        'Transaction Table'[Country],
        'Transaction Table'[Product Name]
    )
var InteresectRows = 
    DISTINCT ( 
        UNION ( EXCEPT ( BaseTab, TransTab ), EXCEPT ( TransTab, BaseTab ) )
    )
return COUNTROWS ( INTERSECT ( 'Crossjoin Table', InteresectRows ) )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
Best Regards,
