You can use either WmPublic pub.client.ftp folder services to ftp:get the file or if the files are accessible/shared to the IS directory locally then you can use pub.file:getFile (loadAs=stream) and then call EDIINT:send (WmEDIINT) service with data/contentType=“application/XML” and map data/stream along with setting other required input params.
Also review the “6-5-2_EDIINT_Module_Users_Guide.pdf” about EDIINT:send and more information about AS2 protocol.
