STUDENT ORDER COMPLIANCE / 學生訂購合規
Find overdue, waste and restricted students
Search by name or Student ID. Red records cannot place a new order until access is restored.
Automatic rule: overdue Form 2 pauses new requests. A waste report requires human review before a manual restriction. / 表單二逾期會自動暫停新申請；浪費紀錄須經人工審查後才能限制訂購。
