How do we add existing defect to a testcase with "import execution results" option.

Karthi Kandasamy

<?xml version="1.0" encoding="UTF-8"?>
<testsuites>
<testsuite name="PyQA Test" tests="1">
<testcase name="Py_Structure" classname="test" started-at="2021-05-31T13:23:10.000">
<failure message="Regression"/>
<properties>
<property name="testrun_defects">
<item>DEMOX-9</item>
</property>
</properties>
</testcase>
</testsuite>
</testsuites>

for example i tried with above xml but it does not add the DEMOX-9 ticket.

Can some one help me on this?@jose
