Record to Record service takes inputs record by record and processes them according to the defined logic using java programming construct, and gives the output one record at a time. User can write Java logic that will be executed in this service. The Java logic has access to Record to Record script service, context of the process flow this service belongs to, input and output Stream handlers, which allow Java logic to access and manipulate input data to generate output and pass it to another service in the process flow.
