[1] Component sends each data record to all of the connected output ports.

[2] Component sends different data records to different output ports using return values of the transformation (DataGenerator and MultiLevelReader). See Return Values of Transformations for more information. XMLExtract, XMLReader and XMLXPathReader send data to ports as defined in their Mapping or Mapping URL attribute.
