Reproducing the Issue
Go to Payables work center and view Payment Runs.
Select a payment run and open the application log of the execution.
In the Results, you see this warning of a supplier account.
Expand the warning, there are two or more invoices listed with open amount. There invoices should have positive amount and negative amount. That is, some are waiting for incoming payment, while others are waiting for outgoing payments.
In this case, the supplier is an account as well. There are supplier invoices and customer invoices in the open item of this business partner.
You can verify with below steps:
Go to Payables work center and view Supplier Accounts.
Select the supplier account and select view, then you can see these open supplier invoices there.
Go to Receivables work center and view Accounts.
Select the same account and select view, then you can see these open customer invoices.
The warning means payment is not created because there are both invoices on the Supplier and Customer sides.
The resultant payment to be created will be a Receivable. Payment Method maintained in this case is Bank Transfer.
The system cannot generate an incoming bank transfer. Such payments appear in the Bank Statement directly once the payment arrives in the bank account. So the payment run does not create the payment.
User needs to manually clear these invoices.
