The startup component of a Script defines the entry point where the Data Processor transformation begins to process the Script. The startup component must appear at the global level of the Script.
You can set a Parser, Mapper, Serializer, Streamer, or Transformer as the startup component.
You can set the startup component from the
Overview
tab of a Data Processor transformation. When you use the IntelliScript editor to set the startup component of a Script, the Script startup component becomes the Data Processor transformation startup component.
