File to File interface without mapping

Hi Experts,

We have to develop 2 interfaces from FTP to FTP using PI without mapping program. Our requirement is, from SAP by running R110 transaction client will create the Files into external FTP location. PI needs to pick these files from FTP and should to place these files into target FTP without changing any thing.

Could any body please tell me the steps how I can achieve this without IR design part step by step.
