The location field from Snapshot is pulled from the employee's effective career history record. If the location value is showing incorrectly in the listing, then it is likely that the value in the impacted employee's career record is incorrect.
To change the location for an employee, follow these steps.
In the Employee zone, click Employees, then Career History.
Open the impacted employee record.
Click on the Career History Tab.
Open the effective career history record.
Ensure the Location field is accurate, then click Save.
The location field in the listing should now reflect the updated location value.
