Invoice documents, including both invoices and credit memos, can be automatically canceled. Note the following:

• If an invoice is canceled, the system automatically creates a credit memo.
• If a credit memo is canceled, the system automatically creates an invoice.

The system copies the amount and quantity for the credit memo/invoice from the invoice/credit memo to be canceled. In this way, variances between the invoice and credit memo or credit memo and invoice are avoided.

Every invoice document can be canceled, unless it has already been canceled or it is itself a reversal document. This can be determined in the document header. The field Canceled with determines with which document an invoice/credit memo was canceled or to which document the reversal document refers.
