If a Bill was matched to a Purchase Order and then the Bill amount gets reduced, there will be a short notification “Check your matching allocations“ for Bills created in ApprovalMax.
In the audit trail will be noted that the request has been updated and therefore resubmitted for approval.
If the Bill amount changes after the approval in Xero, Administrators will receive a fraud notification (if the respective setting is activated).
It is recommended to check the matching allocations for such Bills.
