Answer
Build a small custom scheduled script that reuses the same SQL as your Quick Report as a PL/SQL cursor, assembles the CSV/XML output as a CLOB, and sends it through IFS Connect using Plsqlap_Server_API.Post_Outbound_Message (the same underlying mechanism as posting an outbound BizAPI/integration message) — scheduling that custom script (rather than the Quick Report's own built-in email-scheduling option) is what gets the output routed to IFS Connect's outbound handling, which can then deliver it to an SFTP location via a routing rule the way any other outbound integration message would be.
