The following article provides instructions on how to change the ticket assignment to groups outside of your organization.
When opening a new case, Organization and Assignment Group will automatically default to your home department's organization and its corresponding Tier I Support group. The "Organization" field filters the assignment group choices and service offerings, giving you, the agent, a narrowed-down list of choices. To transfer the case to another organization, simply update the organization you want to transfer to and choose the corresponding assignment group.
On the right side of the case form, you will see the organization field. On a new ticket, this is automatically filled out based on what organization your home department belongs to.
If you still have questions or need additional assistance, please submit a ticket to the ServiceNow department.
