Helper Imany-to-many
Dear All,
I have the following model:
I need to associate a Date Column in Table "Date" to a column in Table "Movimenti".
I tried to relate the two tables with key PROGRESSIVO but it is a many to many.
Do you think I can do something in this case?
THANK YOU
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.
