Warehouses can require unique PO, BOL, or Reference Numbers for carriers by adjusting the Org Settings in Nova.

Key Considerations

📌 Important: To enforce uniqueness, always use the Reference Number field in Org Settings or Warehouse Settings. Do not use the custom appointment fields, as they do not support unique values.

📌 Note: Reference Numbers assigned to canceled or no-show appointments may be reused for new appointments. For PO validation details, check out this article.
