Hi Ashutosh,
My name is Vilas, hope you are addressing your posts to me. Like my name may be you are not getting my comments right. Ariba SIPM very much supports 360 view/reporting for supplier organization including parent child hierarchy. What I have been saying essentially is duplicating SPQ information for a child org from its parent org is not a best practice if the parent and child are separate legal entities.
Regards
Vilas
