Hello,

Is there any functionality where suppliers can be notified after the invoice is approved or rejected? Consider this use case, supplier creates an invoice in Supplier Portal without referring to PO (non-po invoice).

For all non-po invoices, it has to be approved. The approver can decide to approve or reject the invoice.

After the approver rejects or approves the invoice, we want to inform the suppliers that invoice is rejected or approved as the case may be. Is there any functionality to achieve this?
