Inbound documents from OBN do not update the Purchase Order

Hi,

I configured one of our lower ERP instances to Oracle Business Network (OBN) and successfully transmitted a purchase order (850) to a vendor through OBN. The vendor also successfully transmitted the inbound documents (810, 855, and 856) through OBN. The documents were received in CMK; however, they did not update the corresponding purchase order as expected. Please see the screenshots below and advise what needs to be done for the PO to reflect the inbound documents. Thank you!
