I am trying to do set-up for XML Vendor's invoicing.
I have completed all steps in XI for receiving XML invoices from vendors.
When vendor is trying to post invoices to the our XI port it looks like vendor is not getting respose it means we are not receiving any invoices in XI. Do we need to set-up listeners for XI-port? If yes, how to do that? or Do I need to set-up something else?
