We understand that some Managers manage multiple Outlets, while some manage only single Outlets. Toggling the group permission will allow you to give the correct access to the Managers.
To enable this setting, the Admin can navigate to the User Administration page and click on a Manager user, then check the box for "Allow Group Permission". When unchecked, the Admin will need to specify the outlet that the Manager is in charge of.
Managers with group permission can easily switch to other Outlets to view and place order.
Managers with access to single Outlet will only be able to view and place order for their assigned Outlet.
