Foreign Keys

[Chris]

EA version: 3.60.639

In the foreign key constraint dialog for an Association, I tried to create a foreign key by matching the fields up and clicking ok and I get:

---------------------------
EA
---------------------------
Target columns must match
target primary key domain
---------------------------
OK  
---------------------------

It makes sense to match the fields and click ok.. but OK or "Save" both result in the above dialog.

What is the right way to create a foreign key?

The reason I'm trying to create one is so there is something there when I associate the tables.

The error message is raised because the foreign key domain must map to a primary key domain.  That is, the number of foreign key fields and their datatypes must match the number of primary key fields and their datatypes in the referenced table.

What is a domain and where do you set it? I have to have equal amounts of PK/FK's?

I was trying to create a foreign key.. you select matching fields in either table and click ok.. if there are pre-requisites why doesn't the problem tell me instead of a vague message?
