David, that did the trick! I created a computed column c1 which is ssn + ctxt(task_id) + ctxt(qual_type)
Then a standard rule testing for uniqueness with FAIL c2 IN (select c1 from qualified_detail t1 where t1.c1 = qualified_detail.c1) Thanks! I never thought of using a computed column in a rule..

I have not actually tried this, but what about creating a computed column that joins the columns ssn task_id and qual_type together and using that combination in both parts of the WHERE clause?
