Hi,

I am trying to write off a manual supplier invoice with the payment reference added, using the Single Write-Off function in the Supplier Offset Proposal. However, when attempting to approve the offset, I encounter the following error:

ORA-20105: Invoice.NCFREFMAN: For supplier XXXX it is mandatory to enter a Payment Reference

I was able to successfully write off the same invoice using the Mixed Payment window. Is there any reason why the same invoice triggers this error when attempting to write it off through the Supplier Offset Proposal window?
