The documentation portal is undergoing maintenance. During this period, you can't create any new user credentials. If you do, you'll need to recreate the user credential after the maintenance period ends.
Data Validation Option allows you to export and import test metadata from the repositories. Metadata import and export allows users to share tests and allows rapid generation of tests through scripting.

The source-to-target relationships and rules are defined in a spreadsheet. This often happens during data migration. You can script the actual Data Validation Option tests from the spreadsheets.
