As you are getting "With Default" & "Without Default" option, configuration is in place already. There is no extra configuration required.
Instead of clicking Go To - Settlement Rule, directly release the order so that the pop-up message will not come but still settlement rule will be created automatically.
Hope you maintained Default Object type in Settlement Profile & for the same receiver, you maintained "Settlement optional" or "Settlement Required" in Valid Receivers.
IMG - PM & CS - Maintenance & Service Processing - Basic Settings - General Order Settlement - Maintain Settlement Profile
Same Receiver data should be maintained in Technical Objects (Functional Location or Equipment) Master data. SO that, system will bring that data automatically to PM order settlement rule upon release.
