Finding count

Hi sshiny ,

I suggest you to create a calculated column by code as below.

Count of tags with respect to the unique tag owner =
VAR _Tag_Owner_List =
    CALCULATETABLE (
        VALUES ( 'Table'[TAG_OWNER] ),
        ALLEXCEPT ( 'Table', 'Table'[Tag Id] )
    )
VAR _COUNT_OF_LIST =
    COUNTAX ( _Tag_Owner_List, [TAG_OWNER] )
RETURN
    IF ( _COUNT_OF_LIST = 1, 1, BLANK () )

Result is as below.
