Manage relationship of 4 tables

[Grace1]

Hi

I have 4 tables (ie. 1 Primary and 3 Secondary) as in below :

1) All Transport (primary)

2) Dealer master ( Destination = DealerName)

3) Yard master (FromYard = YardName)

4) All Budget (CustomerName = Name)

I want to achieve below dashboard but don't know to manage the relationships of the 4 tables.

Appreciate any advice. Thanks.

HI @Grace1,

After research on your screenshot, I found you can try to use 'Yard master' as bridge table to link other tables with 'customer name' column.('one to many' relationship)

Hi Xiaoxin Sheng,

I try to create relationship using ' customer name' as the link between the other tables but has error "You can't create a relationship between theses two columns because one of the columns must have unique values."

HI @Grace1,

Current power bi not support 'many to many' relationship, you need to use unique records table as the bridge to link other tables.

If you can't ensure which table contains unique records, you can try to manually create one to link other tables.

Sample table:

Cusotmer Name =
DISTINCT (
    UNION (
        VALUES ( 'All Transport'[CustomerName] ),
        VALUES ( 'Dealer master'[CustomerName] ),
        VALUES ( 'Yard master'[CustomerName] ),
        VALUES ( 'All Budget'[CustomerName] )
    )
)
