How do we get the incoming invoice? We receive such an invoice by ordinary mail. It is usually not in the delivery of goods itself.

We then check the booking of the receipt of goods in the SAP-system. To do so we have to look at a material document.

Should there be a mistake in the invoice we have to write to our supplier immediately and ask him to check it and send us a new invoice. But if the invoice has been checked for its mathematical correctness and the correctness to the purpose then we mark the invoice document with an annotation “correct to the purpose and mathematically”. We then call the adequate SAP-application and implement the incoming invoice.

In a normal case of a complete delivery the SAP-system automatically books while saving the incoming invoice in “financial accounting.” Please note: While saving the incoming invoice the SAP-system creates an open-item-accounting of the total amount of the invoice. The SAP-system always knows exactly when this item is due.
