  Consult with Colleagues: If you are unsure, consult with colleagues or your purchasing department to confirm whether the PO is indeed needed or if it can be modified.
  System Configuration: If you believe this is a system error, consult with your SAP administrator or IT department to review the configuration settings related to purchase orders.
