Sorry, misunderstood.
Got it now, you are looking for example csv file for loading Documents of Doc sub types.
Have you checked WCDataLoadGuide.pdf (Windchill Data Loading Reference and Best Practices Guide Windchill 10.1 M040 April 2013).
Also you can check here for example files <wc_home loadfiles=" pdmlink="> or <wc_home loadfiles=" generaldocs.csv=" and=" generaldocs.xml=">. These files doesn't have IBAs, but you can add and run the test.
Thanks
