Disallow specific invoices from being paid on the portal.
Disallowing payment on specific invoices
You can disallow payment on specific invoices by adding the optional field "PAYONLINE" (Type Yes/No) to the invoice header and setting the value to "No". This invoice will still appear in the available invoice list but the user will not be able to select the invoice and a pop-up message will inform the user that the invoice is not available for payment on the portal.
If you are using Order Entry to generate sales invoices you need to add the optional field to orders, shipments and invoices. Make sure that you set the optional field to "Required" and "Auto Insert". You also need to add the field to AR Invoices. During processing and day-end the field value will be passed from the OE order to the AR transaction.
