Hi @Alex_Hasan,

You should first create relationship between two tables, through the same field:

And then you can make 1 to many relationship based on “Customer Key.

@Alex_Hasan , In the customer table, the customer key should be unique and should not have a blank value. then you should be able to create a 1-M join

Yes, customer key column is unique and does not have a blank value. But how to create a customer key column in factsales table?
