PowerPivot Relationships Not Working - Multiple Tables

问题

I have created this model:

Vendor_Key table contains the unique Vendor Numbers of table 1,2 and 3. The only table that has unique values is the Vendor_Key table.

However, I can't get the relationships to work:

PowerPivot can't identify the relationship either.

Nonetheless, the relationships between Vendor_Key and Table_4 works correctly, but it doesn't when I add a field from another table.

I have found these articles related to the subject, but I think this issue may more complex since I am trying to join several columns of multiple tables:

Please advise.

Thanks
