RE: [MS_AccessPros] Relationship Definition


In order to enforce referential integrity, each row in the child table, Product, MUST relate to a record in the parent table, Product Class. You can still create a relationship. You just can't apply referential integrity.

I have 2 tables:

Product Class



The Product table has a field Product Class that relates to the Product Class table. This field in the Product table is optional.

 I am trying to define a Relationship with 'referential integrity' between the Product Class and the Product table, but because I have records in the Product table that dont have the Class filled in, I am getting a message 'Product violates referential integrity'. Is there any way around this?. I have tried all Join Types but I am getting the same message on all of them. 


Thanks for your answers.
