DAX Show matching values from both tables where there is a many to many

Hi

I have two tables where there is a many to many relationship.

I want to see where the IDs match and are also occurring more than once:

e.g.

Table 1:           Table 2:          Output Table

ID                      ID                        ID

12                      10                        14

14                       14

14                      14

14                       15

15

15

Many thanks for looking!

Hi @laganlee 

please try

Output Table =
VAR T1 =
FILTER (
'Table 1',
COUNTROWS (
CALCULATETABLE ( 'Table 1', ALLEXCEPT ( 'Table 1', 'Table 1'[ID] ) )
) > 1
)
VAR T2 =
FILTER (
'Table 2',
COUNTROWS (
CALCULATETABLE ( 'Table 2', ALLEXCEPT ( 'Table 2', 'Table 2'[ID] ) )
) > 1
)
RETURN
DISTINCT ( INTERSECT ( T1, T2 ) )
