target definitions overview - Informatica

To use flat files as sources, targets, and lookups in a mapping, you must import or create the definitions in the repository. You can import or create flat file source definitions in the Source Analyzer. You can import or create flat file target definitions in the Target Designer. You can import flat file lookups or use existing file definitions in a Lookup transformation.

Note:Because source definitions must match the source, you should import file source definitions instead of creating them manually.

Creating Sessions with Flat File Sources and Targets

When you create sessions using file sources and targets, you can override some properties you define in the Designer. When you create a session with a file source, you can specify a source file location different from the location you use when you import the file source definition.
