I have not had chance to install 5.4 yet and it would be great if metadata will have ability to carry FILENAME with the message through the engine.
Jim is absolutely right. I have another set of procs that do set OBFILENAME key list value in message metadata. Let me know if you want me to send that to you via e-mail or whether I should post it on the board.
Essentially it takes file name from inbound Fileset-Local or Fileset-FTP and stuffs it into userdata in metadata.
Drop me a message here or e-mail me.
