When adding a new external database to a versioned schema in the development environment, add the external database in the current version. You can specify connection and subsequent database modifications in the latest version.

Use the + and - label in the upper-left column of a table header to include or exclude rows (that is, toggle the selection of rows).

The External Schema Wizard is a wizard-style dialog that consists of 12 steps, each represented by a sheet of the dialog. Use the Next > and < Back buttons to navigate forwards or backwards through the steps, or explicitly to a step by tabbing the sheet tab. No step is enabled until the previous step has been completed.

As the changes are committed at each step, you can click the Close button on any sheet to close the wizard and resume your external database transformation later, if required.
