Can the original voucher of the original voucher be removed after red-flushing?

You can't. In principle, they will also give you a negative invoice, and then you will rush it.

Because if they don't issue negative numbers, they have already paid taxes before issuing invoices. If they don't issue them now, it means paying more.

In addition, there is a principle that must be kept in mind. Everything entered in the account, including vouchers and attachments, cannot be moved. Only the following items can be used to explain the reasons for the modification. Otherwise, you can change it casually, and the whole account will be messed up, right?
