Hi April, the best way to accomplish this is through assignment rules. Please refer to the following link for further information about it: http://wiki.servicenow.com/index.php?title=Defining_an_Assignment_Rule_for_Incidents#gsc.tab=0

Assignment rules are evaluated in order, and it will stop evaluating as soon as one of the rule succeeds. The way of defining a default one is to define one with the highest order which is always assigned if none of the other assignment rules succeeded.

If within your CIs you have defined your support groups, then an assignment group could look like the following:

Applies to (condition😞

        - Configuration item is not empty

        - Configuration item.support group is not empty

Script:

        current.assignment_group = current.cmdb_ci.support_group;

Simple as that!!

Then you can have a default assignment group which just leverages the Assign To and there you can select the group that should be defined per default.

I hope this is helpful!

Thanks,

Berny
