During this stage, you associate a record parser with the flat file schema that will process flat files inbound to the Integration Server. You also specify how you want the record to be identified after it is parsed. For more information about defining the record parser, see Specifying a Record Parser. For more information about specifying a record identifier, see Specifying a Record Identifier.
