You use the test data editor to create and maintain test data containers.
The parameters in a test data container are maintained independently from any test script. You can specify a maintenance system for the test data container, and can also specify a different target system for each parameter.
You can download a test data container as an XML file.
You can create variants containing different parameter values. There is always a default variant called ECATTDEFAULT. This contains parameter values that are used if a corresponding value has not been entered in a variant.
Default values in the test data container override the default values of the test script if they are referenced by the test configuration. That is, when a field referenced from a test configuration contains no value, the default value from the test data container is checked, and when that has no value, the default value in the test script is used.
