Depending on operational and accounting requirements, changes to the segment and the spreadsheet are no longer possible once the invoice number has been assigned. Incorrect invoices are corrected by issuing a credit note (correction or cancellation invoice).

1. Right-click on the incorrect invoice segment and select  Create credit note.
2. Confirm the name suggested for the new segment or enter a different name that signals the relation to the original invoice.
3. Click on  Spreadsheet and confirm the prompt by clicking on Save.
4. A consecutive, unchangeable number is generated automatically or manually when a credit note is created. Confirm the prompt by clicking OK.
5. Select a different  Invoice template by clicking on  <Standard> if needed.
6. In the credit note, the invoice amount is set to minus in order to balance out the turnover.
