  Use a Unique Purchase Order Number: If you find that the purchase order number is indeed a duplicate, you will need to create a new purchase order with a unique number.
  Review System Configuration: Check the configuration settings in the VMI or APO module to ensure that they are set up correctly to handle purchase orders.
  Data Cleanup: If the error is due to data synchronization issues, you may need to perform a data cleanup or reconciliation between the systems involved.
