Problem
The only purchase order added to an invoice was numbered as "002". This happened because another user was creating purchase order "001" at the same time.
Solution
Purchase order numbering discrepancies occur when multiple users create or cancel purchase orders simultaneously.
Resolving Discrepancies in Purchase Order Numbering
Check if another user is creating a purchase order.
Ask your manager if they were adding a purchase order at the same time.
Confirm if the manager had the purchase order screen open.
Understand that if a purchase order is being created by someone else, your purchase order will get the next available number.
If a purchase order number seems incorrect, check with your team to see if there was a purchase order being created or canceled at the same time.
