Hi Nishanth & Arif,
Thanks for your replies. Just to clarify, my issue is not having insufficient access. And to answer Arif's question, we don't use NWBC, we only use portal.
Thanks for the clue. Yes, I do not see the 'master data' tab at all in portal. Where am I supposed to see it and how do I enable it? We have a standalone GRC 10 Access control application only (PC or any other component is not implemented at all). I am not sure what org was created while creating the ruleset as that was done by a different person who already left the company.
In summary, my primary question is still the one noted in the subject line, and it is still unanswered 
If the child org unit needs to be updated, please specify which child org unit and where? [ There is nobody else to maintain GRC at my company now - so whatever it is I need to do 
]
