many-to-many

Hi LoryMenCR ,

I would not recommend that you create any more relationships between these two tables, as both of your tables already have a relationship with another table:

If say you want to continue to create a relationship between the table Date and the table Movimenti (whether it is many-to-many or many-to-one or one-to-one), it will form a closure relationship, which is highly discouraged in Power BI Desktop because multiple active relationships create conflicts and multiple relationships may lead to unclear dependencies between tables.
