The correction invoice process is used to correct instant invoices and outgoing supplier invoices which contain incorrect information by creating a correction invoice. A correction invoice can be generated only for invoices of which the status is Posted, PostedAuth, PaidPosted or PartlyPaidPosted. It is not possible to correct advance invoices using this process.
An invoice can have only one correction invoice connected to it. However, it is possible to make further corrections by creating a new correction invoice which will be connected to the first correction invoice instead of to the original invoice.
A correction invoice is generated for an invoice by selecting command Create Correction Invoice in the Instant Invoice or Outgoing Supplier Invoice page. This opens the Create Correction Invoice dialog box in which the invoice date and the invoice type of the correction invoice being generated have to be specified. The invoice date entered in this dialog box would be the payment term base date of the correction invoice. Therefore, the invoice due date, the installment date and the discount due date of the correction invoice will be calculated based on this date.
All other information except the invoice date and the invoice type will be copied from the original invoice to the correction invoice. For each original invoice line, two invoice lines will be created in the Lines section in the Instant Invoice or Outgoing Supplier Invoice page for the correction invoice. The first line would be a copy of the original invoice line. The second line is a correction line which corrects the original invoice line by reversing the quantity, tax amount gross amount and the net amount to make the invoice amount zero. The correction line is not editable and therefore, the Preliminary Update Allowed will not be selected. The copy of the original invoice line can be modified manually before printing. Once the invoice line(s) is modified and saved, the invoice fee and the rounding will be recalculated based on the revised invoice amount.
In order to distinguish the correction invoices from the normal invoices, a different print layout will be used to print correction invoices. The text Correction Invoice will be printed on the header of the correction invoice and the invoice date of the original date will be printed as the reference date. Below the header, the printout will be divided into the following sections.
