Configuration for sending Purchase order in XML format to a middleware using OPD

[nn25]

Dear SAP Experts

Regarding our requirements, we need to implement an SAP S/4HANA on-premise solution to send a purchase order in XML format via the EDI channel in OPD. The purchase order will be transmitted to a middleware system, rather than directly to the vendor.

We would appreciate your guidance on the following questions:

1. Can a purchase order be sent to a third-party system in XML format via the EDI channel in OPD? If so, is this still feasible if the third-party system is defined as a logical system rather than a vendor?
2. Based on our requirements, can this process be fully managed using OPD, or would it be necessary to switch to the NAST method?

Additionally, I would be grateful if you could provide a relevant SAP Note or a detailed tutorial outlining the necessary steps for implementation.
