Reversals 
Use
Invoice documents in Invoice Verification are either invoices or credit memos. These documents can be cancelled. There are two different cases:
- If an invoice is cancelled, the system automatically creates a credit memo.
- If a credit memo is cancelled, the system automatically creates an invoice.
The system takes the amount and quantity for the credit memo or invoice from the invoice or credit memo to be cancelled, thus avoiding any differences between the invoice and the credit memo or the credit memo and the invoice.
Prerequisites
An invoice document can only be cancelled if:
- it was posted in Logistics Invoice Verification
- It has not already been cancelled
- It is not a cancellation document for another document

When you cancel documents in Logistics Invoice Verification, the document line items are not automatically cleared in Financial Accounting. We recommend that you periodically clear such items (using daily background jobs, for example).
Procedure
To cancel an invoice document, proceed as follows:
- Choose Logistics Invoice Verification
®
Further Processing
®
Cancel Invoice Document.
The initial screen for reversal appears.
In the fields Invoice doc. number and Fiscal year, enter the data for the invoice document you want to cancel.
In the Reversal reason field, select the reason for cancelling the invoice. This allows you to differentiate between different types of cancellations.
You can display the document to check. Choose Display document to do this. You can look at the items of the document to be cancelled. Return to the initial screen by choosing Back.
Choose Invoice document
®
Post reversal doc.
Result
The system automatically posts a credit memo or invoice. You receive a message.
- The system checks an invoice created as a result of cancelling a credit memo for variances. If variances occur, the invoice may be blocked for payment. If it is, a message appears.
- When you cancel an invoice or a credit memo, the system creates an invoice or a credit memo from information contained in the document to be cancelled. In the simplest form, the postings in the invoice or credit memo are simply reversed.
- However, this is not always possible. If, for example, an invoice is cancelled in which a material was debited, the postings can only be reversed if there is enough stock when the invoice reversal is posted. If there is not enough stock, the reversal posting is made proportionally: the part for which there is sufficient stock coverage is posted to the stock account, the remainder to a price difference account.
- When you cancel an invoice or credit memo referencing a purchase order, you cannot reverse the account movements originally made if a further invoice with a different price was posted after the invoice that is to be cancelled.
