Error I am unfamiliar with

[PrivateAnalytic]

Hello all! I have come across this error from a table I created. I've had no issues at all until this evening. How would one resolve this?

Hi @PrivateAnalytic ,

The one side of these two tables does not contain all the value of the many side.

Please check and add the missing key which is in the manyside but not the oneside to the one side.

Best regards.

Hi,

After refreshing the table (that is shown in your message as ''), Power Bi finds the null value for the Primary Key column.

I tried to enter row in my table and put null for the primary key (field that I used as a relation column), and I received the below message :

After I put value to the particular column it is refreshing properly.

Appreciate for Kudos
