Why are prior-period Billing Lines appearing in my Billing Schedules and Member Invoices, Statements & Billing reports?

By default, the Billing Schedules and Member Invoices, Statements & Billing reports will bring forward all outstanding/unpaid Billing Lines from prior-periods to ensure that you don't lose sight of unpaid items as you move to a later period(s).

However, you can override this with the Include B'fwd Due Balances? filter. Just set this to 'No' to prevent prior-period Billing Lines appearing.
