Hi Pruthvi,
I don't think your issue is caused by the access rights or any of your actions. This seems to be a new issue.
I just checked with a user that has all the Advanced Reporting rights but Administer and was able to create and save an Ad Hoc view correctly.
Please could you see where exactly you tried saving the Ad Hoc view? Try saving it in the User's personal folder and see if that works.
When this error appears : can you check if the Ad Hoc View still gets created? Does it appear immediately after clicking on Save?
If you still can reproduce it provide your jasperserver.log from $JSTomcat\webapps\reportservice\WEB-INF\logs for review.
Looking forward to hearing from you.
Kind Regards
