You maintain test configurations in the test configuration editor.

A test configuration contains references to one test script and one system data container. It can contain references to several test data containers but need not have any.

The test configuration references the import part of the data interface of the test script. You can enter test data manually to create variants. Additionally, you can use variants from the test data containers that you reference.

There is at least one default variant called ECATTDEFAULT. This contains parameter values that are used if the corresponding values in the variants are not filled.
