You don't mention the error but its probably a mutating table right?

If update_cedr_custs reads exactly the one row from ar_customers that was modified -- the best solution is to PASS the :new.columns into update_cedr_custs from the trigger instead of having it read the table (best cause it'll work AND its faster).

If update_cedr_custs reads more then just the modified record -- see http://osi.oracle.com/~tkyte/Mutate/index.html for how to do this.
