I send my purchase orders (PO) to a supplier by printing the BearBuy PO and then sending it via email. Is this step necessary?

All BearBuy POs except for payment request type forms and after-the-fact POs are automatically sent to the supplier through BearBuy. POs should not be printed and sent to the supplier outside of BearBuy. 

POs may be sent electronically (cXML) via fax or email to the supplier in the method that they specify. To see how a PO was sent to the supplier, navigate to the PO Status tab. In the Document Status section of the page, you can see how the PO was sent to the supplier in the Distribution section.
