However, if similar scenario invoice is posted with different reference, I am not able to perform reversal via Fiori Apps Supplier Invoices List. The error Check whether document has already been entered under number XX &amp; &amp; will pop up. The error message is referred exactly to the invoice number that I am going to perform reversal. Does that mean for all Invoice that have Reference info should only reverse via MR8M and not via Fiori Apps?&nbsp;</P> Sun, 23 Mar 2025 09:02:52 GMT https://community.sap.com/t5/enterprise-resource-planning-q-a/issue-when-performing-reversal-via-fiori-apps-supplier-invoices-list/qaq-p/14053826 jialey 2025-03-23T09:02:52Z https://community.sap.com/t5/enterprise-resource-planning-q-a/issue-when-performing-reversal-via-fiori-apps-supplier-invoices-list/qaa-p/14069577#M4212963 <P>The error occurs because Fiori App checks the reference field for duplicates, unlike MR8M; invoices with a reference number may need to be reversed using MR8M unless the Fiori app logic is adjusted.</P> Tue, 08 Apr 2025 12:02:27 GMT https://community.sap.com/t5/enterprise-resource-planning-q-a/issue-when-performing-reversal-via-fiori-apps-supplier-invoices-list/qaa-p/14069577#M4212963 HakanHaslaman 2025-04-08T12:02:27Z
