Can't determine relationship between fields

[jch]

I have 2 tables:

1. Table readin contains a calculated field :

Actual Date = if(SEARCH("/",readin[Actual], 1, -1) > 1,DATEVALUE(readin[Actual]))

2. Table DimDate contains a date and associated categorical variables for charting. I also created this column:

DateKey = datevalue(DimDate[Date])

How come adding a relationship between these 2 fields throws the error Can't determine relationships between the fields?

Thanks in advance

Hi @jch ,

Could you tell me if my post helps you a little? If it is, kindly Accept it as the solution to make the thread closed. More people will benefit from it.

Or please provide me with more details about your table and your problem or share me with your pbix file after removing sensitive data.

I appreciate your help on this. The answer ended up being

In a one-to-many relationship, you can only filter the relationship by table like table2, but not vice versa.

Hi @jch ,

You are trying to use two or more fields from tables that are not related. You need to remove the unrelated fields from the visual and then create a relationship between the tables. Once you have done this change, you can add the fields back to the visual.

@jch what @TomMartens  suggested, but why you are adding DateKey column in Calendar table? What is the type of both the columns? Is it date?

Hey  @jch ,

create a pbix file that contains sample data, but still reflects your data model. Upload the pbix to onedrive or dropbox and share the link. If you are using Excel to create the sample data, share the xlsx as well.
