Supplier Portal – Validation of Attachments and Invoice Data Consistency

Is there a way to validate that the attachments uploaded by a supplier in the Supplier Portal correspond to the same supplier for whom the invoice is being created, and also ensure consistency between the entered invoice data and the uploaded documentation?

For example, we have a case where an invoice is being created for supplier (SUPPLIER-ABC), but the attached documents actually belong to a different supplier (SUPPLIER-BCD). This creates compliance and audit risks, as there is currently no automatic validation that the uploaded files match the supplier or support the data entered in the invoice.

Ideally, the system should check not only the consistency of attachments but also verify that the key invoice data (supplier name, tax ID, amounts) aligns with the supporting documentation.
