Selecting Data Loader Settings
Data loading is used to initialize and populate the Windchill database with base or demonstration data. The base data for all of the installed Windchill products must be loaded before you can use Windchill.
If you choose not to load data using PSI, you must manually load it after PSI installs your solution using the instructions in the section Database Initializing and Data Loading.

If your system has an organization named “Demo” then the loading of demonstration data will fail. To avoid this failure rename your organization.
In the Define Settings section, determine the appropriate selection
