To create the billing for Community Transition, the data is entered on the Scheduler, just as any other Event is documented. With one exception. When you select "Community Transition" from the Category dropdown menu, there is an additional field "Community Transition Billing" that is displayed. This is where the billing amount is entered. The service code does not need to be entered, since it is always gong to be 'ACT'. The billing units will always be 1 unit.
The remainder of the Event Details is populated as any other Event. Note that selecting a staff is optional, but a client is not optional.
