Hi Kanchiraju,
You only need to use a dummy service interface to do your scenario, you can follow this example **************** - File-to-File Scenario without creating Repository Objects, i know it is abut an old PI release but the configuration is similar, also you can do it with the ICO object.
With ICO object you have Satish example: Re: Step by step File to file scenario using ICO in PI 7.1
