Can I use more than one PO number on a single use certificate?


I am using a single use certificate with more than one PO number so I can make a customer exempt for certain transactions.  However, it is not working to exempt on all the PO numbers just the latest added one.

  • Single use certificates will only work to exempt on the most recently added PO number, so although you can have multiple numbers on the certificate, only one will work at a time.
