Power BI: relations plusieurs-à-plusieurs, bonne pratique ?

J'ai deux tables de faits qui partagent une dimension. Power BI crée une relation plusieurs-à-plusieurs.

Est-ce que je devrais créer une table de pont (bridge table) ? Quel impact sur les performances des mesures DAX ?

Yes, use a bridge table. Create a distinct dimension with unique keys, relate both fact tables to it as many-to-one, and hide the raw many-to-many. DAX measures stay simple and USERELATIONSHIP becomes unnecessary.
