Relationships with missing data

screenie.png

Hi all. I need to create a relationship connecting table 1 and table 2.

If I create a link using only ID 1, some data will be lost. Likewise for ID 2.

Is there a way of using both ID 1 and ID in table 2 to link to Table 1?

Thank you

Hi @Anonymous

 

After splitting the first table. You may set the relationships as below. Then you may create a measure to get all the FirstName.

UpdateFirstName =
IF (
    MAX ( '1(1)'[First Name] ) = BLANK (),
    MAX ( '1 (2)'[First Name] ),
    MAX ( '1(1)'[First Name] )
)

@Anonymous Hmm, you can split the first table into two separate tables (FirstName and ID1) (FirstName and ID2). Then link the table2 to these two tables by ID1 and ID2.

Unfortunately your solution provides this. The first Name and Last name should show all data from both columns

Hi @v-cherch-msft

 

Using your method, will I have to create a new measure for every subsequent column e.g.

UpdateFirstName, UpdateEyeColour,UpdateShoeSize etc?

 

Many thanks
