The Primary Key must reference 1 or more columns; there are none

[crmp-1]

Hi Experts,

I created the datasource of sqlserver 2008 in the teiid designer(jboss developer studio).

and then I selected the tables as the metadata , every tables were listed in the left sources folder.

but I found  below errors in the problems window:

The Primary Key must reference 1 or more columns; there are none.

Is there anyone know about this issue

That does not look familiar.  Can you tell which table(s) are affected?  And if there is a primary key defined for them in the database?
