The GU/CREDIT NOTE with the number 5379012 was posted as an invoice (KR – SAP Bschl 31) during manual or OCR pre-entry and paid accordingly.

Only the systematic and comprehensive preparation and analysis of the SAP vendor data in EVV GmbH ‘s tools led to a correction 1.5 years later. Interestingly, the payment of a credit note as an invoice deducts twice the value (€7,710.48). The correction must therefore be reversed twice.

SAP internal validations were unable to flag or prevent this error, which occurred several times and across suppliers. EVV GmbH is consistently working on the integration of AI-supported analyses in order to systematically identify sources of error that have so far only been insufficiently checked.
