Before creating a purchase order to send to a vendor via Pubnet, you must first make sure the vendor has Pubnet information entered in your vendor file, and that the Pubnet information is attached to the system type for which you are creating the PO. If the vendor specified on the Purchase Order does not have Pubnet information entered, you will not be able to send messages to them via Pubnet.

To Enter Pubnet information on the vendor record

1. Access the Vendor Maintenance module.
2. Use the Quick Search to locate the vendor.
3. The vendor address card will be displayed on the screen.
   
4. Make sure you are accessing the system address card for the same system you are creating the PO. For example, if you are wishing to send a textbook PO, set the system to the "Textbooks" system type.
   
5. Once you have selected the Textbook system address card, switch to the Parameters tab of the vendor.
6. Access the Pubnet information area of the vendor Parameters tab.
   
7. Enter information in the following fields:
   Encoding: Choose Pubnet USA or Pubnet Canada based on your location. 
   SAN: Enter the vendor's SAN number.
