I am trying to insert a record to shop order history when configuration change. I set an event when the configuration change triggers a script. However It gives an “mutating, trigger/function may not see it” error. To solve that I decide to use background jobs. I called the “transaction_sys.deferred_call” procedure from PL/SQL Developer. When I control the background jobs. It gives an error about the argument but I could not understand.
