DSN - Unknown Assignment on SE Purchase Order

[monaliz_p_dizon]

As we are trying to implement Digital Supplier Network (DSN) to the client, I would like to know if Ariba Network can support PO with "Unknown" account assignment.

Currently, the client have PO setup with "U" (Unknown) account assignment, the account assignment is not visible in the PO, but rather reflected 'behind the scene'. The client would like to understand how the process would work in AN, how does the supplier know on what Cost objects to use when sending the SES. Is there a flow in Ariba wherein vendors will be notified of the specific cost objects?

Thanks!
