(1) When uploading the red-ink information table, it is prompted that the blue-ink invoice has authentication records and cannot be uploaded. In fact, the existence of authentication records in the system means that the invoice has been authenticated by the buyer. The buyer should apply for the red information form and submit it to the seller, who will issue a negative invoice. (2) The blue invoice has not been issued this month or last month, so it cannot be uploaded. When the seller washes the red-ink invoice information, he checked "Unable to deliver due to wrong invoicing and other reasons". When applying for the scarlet letter information form, only invoices issued this month or last month that have not been delivered to the buyer can be selected. If this is not the case, check "Buyer rejected due to wrong billing" to complete the upload. (3) When this prompt appears, you must first verify whether the amount in the information table is accurate.
