Error message 'NPX' has been added to Transaction ZOPENITEMAP, the AP Open Items Report. Payment Method Supplement 'NP' is required for ACH payments to vendors with an email address in the ‘Clrk's internet’ field (Vendor Remittance Email Address) on the vendor master record.
ACH Payments made to vendors with a remittance email address in the vendor master and without 'NP' in the Payment Method Supplement field on the payment document will be held for payment until corrected. The error message is necessary to inform Accounts Payable staff why the document has not been paid.
