If an invoice fails validation, it is sent to the Exception activity.

An invoice can fail validation for the following reasons.

• The business unit for the invoice cannot be determined.

• The vendor specified for the invoice cannot be determined.

• The invoice Invalid Reason field is populated after invoice import.

• The invoice has incorrect header or lines values.

• The invoice is a duplicate.

• The invoice was rejected by the coder or the approver.

• The invoice was routed to the Exception activity within the customization process after the invoice import.
