Detect if running in background

We implemented a modification where triggering an action creates a background job executed by the IFSAPP user to update certain data.

We also have an event configured to prevent modifications to this data when the user is IFSAPP.

How can we adjust this event so that it is not triggered when the user is IFSAPP and the action is executed through a background job?

is it possible?

Thank you in advance

DECLARE
cf$_userid      VARCHAR2(100);
BEGIN

   -- Récupérer l'utilisateur IFS
   cf$_userid := ifsapp.fnd_session_api.get_fnd_user();

   -- Interdire l'utilisateur IFSAPP
   IF cf$_userid = 'IFSAPP' THEN
      Error_sys.Appl_General(
         'SepaPaymentAddress',
         'IFSAPPMODIFYRIB: IFSAPP n''est pas autorisé à modifier les RIBs'
      );
   END IF;

END;
