How am I notified that my invoice is rejected?

SY notified you in the portal:

• A notification is shown on the portal home page that an invoice is non-compliant
• The invoices in error can be identified in the invoice list by the status "Non-compliant"
• On the homepage, the indicator is incremented on the "Reject invoices" and "Non-compliant invoices" tiles. SY also sends notifications to the address configured for the account
