Hi , I am trying to transform CSV file into SDA3 format by using Studio code. I am getting "No Stream contained in StreamContainer Request" Error at the business operation after converting CSV file to SDA3 Format but not able to generate the file in business operation  Is there any way to to convert the pass through Ens.StreamContainer in Business process or Do i need to Create a custom Business service to change CSV to SDA3 Format?     Thanks, Smythee
