If you are trying to change only one network, it can be controlled at the network header.
Go to the network header in the change mode. Pick the control tab, go to the field labeled Components, and change the field to “Immediate”. The field technical info is CAUFVD-AUDISP
If you want to make the change the standard on all networks, GO to configuration OPUU and set the appropriate default in the network profiles, using the field labeled RES./PURC. req., to 3. (field label TUT1-AUDISP.) This will cause all of the networks that use the profile to default to “Immediate”.
