Hi,

We are interfacing Purchase Orders from JDE to Oracle Procurement Cloud with SOA as a middleware. SOA is calling Cloud PO REST API to create the Purchase Order in Procurement Cloud.

Now we are exploring option on how to interface attachments from JDE to Oracle Procurement Cloud as part of the Purchase Order.

Is there any document available?
