If you have Teams activated, here are the steps to assign a Team to a case.
Navigate to a case.
Click 'a' on your keyboard, the Workers header, or the arrow next to the case status on the upper right corner of the screen.
Select Edit Assignments.
A pop-up window will appear.
Click the Team drop-down menu and select the desired team.
Click Save.
The assigned team will be reflected in the case index below the case name and the date of loss.
NOTE: Selecting a team in the Edit Assignments pop-up will not auto-populate the assigned workers for that team, it's for reporting purposes.
