Depending on your organizational practices, you may have test cases captured by Ketryx that you don't want reported in your traceability matrix. These test cases can be "hanging" without an upstream trace to a requirement. To remove this line from your traceability matrix, you will need to apply an Advanced Setting: Traceability Configuration.

 "columnForTestsWithoutTestedItem": ""

By default, tests associated with the project will appear "hanging" even when there is no upstream design input or output.

With the configuration above applied in the advanced settings, this row of "hanging" tests is removed.
