You have the ability to stop users from creating delivery addresses in the booking screen. This can be a control measure to ensure that only approved delivery locations are used by the booking staff.

EDI and portal bookings can still create new delivery addresses with the parameter turned on 

1. Go to Settings -> Parameters

2. Search for 'stop'

3. Find the parameter  'stop_create_delivery_address_on_booking'

4. Select the drop down in the Value column and select Yes or No

    NO - this means the parameter is OFF and users can create delivery addresses on bookings.

    YES - this means the parameter is ON and users cannot create delivery addresses on bookings.
