Invoice correction (reversal)
In day-to-day business, invoices occasionally have to be subsequently corrected by a cancellation because they were issued incorrectly or goods delivered were returned. Whether a price has been corrected or a delivery cancelled – this is always an invoice correction. An invoice already issued may only be corrected by a credit memo or cancellation. Inventories of cancelled articles are automatically corrected in desk4 and corresponding profits and sales are adjusted in the statistics. The cancellation invoice must refer clearly to the original invoice and is always generated from an invoice in desk4 for this purpose. All relevant booking accounts are provided by desk4 when they are transferred to DATEV.
