Facing issues in Cardinality (Many- Many)

Hi Folks, 

I am facing issue in Data modelling in power BI the issue is the power BI it self taking Many- Many cardinality for Two tables in that Many - Many cardinality I having one popup like " This Relationship has Cardinality Many- Many ,this should be only be used if it is expected that neither column (table 1 and table 2) contains Unique values, and that the Significally different behaviour of Many- Many relationship is understood" but I am changing the cardinality Many-One forcefully power BI unable to process that and I am getting error like " the Cardinality selected isn't valid for this relationship "... Is there any solution for this.. please suggest any solution fo this it's helpful for me and project

Thanks in advance

You can create another table(lookup) which will have a unique values from those two tables and then connect both the tables to the Dimension/Lookup Table with Many to One relationships and utilize the column from the lookup table in your visuals.
