How to reflect Child Test plans execution status from the Master Test Plan?

We've seen in several documents around the Rational documentation such as:
https://jazz.net/downloads/rational-quality-manager/milestones/4.0.1M4?p=news#birt
and
https://jazz.net/help-dev/clm/index.jsp?topic=%2Fcom.ibm.jazz.reports.doc%2Ftopics%2Fqm_c_mstr_chld_rels.html

that RQM supports a master-child relationship between test plans and with this we should be able to track the child test plans execution status from the Master Test plan perspective by using the OOTB report "Execution Status Using TCER Count".
We're running  RQM 4.0.0.1 and as per the above references this should have been enabled from 4.0 and onwards, though the box "Evaluate Test Plan Master-Child Relationship" from where we should be able to select "Yes" or "No" is not showing up while configuring the report.

How can we report the child test plan execution status from the Master Test plan execution status?, Is there a way to enable this option from the Project Configuration or is something at the Jazz Admin (server admins) side?
