Hi Raj,

Thanks to reply,

Below cardinalities, when compare with joins one to many means right join like that are any difference.

cardinality                joins(inner join, left join, right join)

one to many            -  Right Join

many to one            - Left Join

one to one              - inner Join        

Thanks

HI @Anonymous,

In actual, power bi not contain for join modes which you mention. 

Current power bi will try to use inner join mode to analyse relationship and records, through relationship mapping. So it only allow one active relationship between two tables.
