Hi Kanna,
Please check suim transaction and identify which all roles are containing authorization object as mentioned by you.
You can conclude following:-
1. If there are more than 1 role which contains the auth object as mentioned by you, please check out of that how many of them are assigned to user who is executing the report. All such auth object which are assigned in different roles shall be restricted to the profit center as required by you
2. If there is only one role, please check note as suggested by Cristiano and ensure that there is no other auth object which is granting access to the reports
Hope this helps
Thanks
Nishu
