Cancelling Invoices In AP

Period end scenario where current and previous periods are open. If one cancels an invoice, it is cancelled in the current open period as opposed to the previous period that the invoice was originally posted in.

Is  this wrong? Should not the invoice be cancelled in the SAME period the invoice was originally posted in if that period is still open?

Similarly, if the current AP period is not open yet but the previous one (that an invoice was created in) is, it is not possible to cancel  the invoice as Oracle wants to cancel it in period 12.
