Permissions granted to user are insufficient?

Hi all,

I was trying to deploy SSRS report in Report server and getting an error like below.

Error:

The permissions granted to user 'AnilKumar\Anil' are insufficient for performing this operation.

Here "Anilkumar\Anil" is the system administrator of windows account.

Can anyone suggest the way to resolve this issue. Thanks in advance!!

Thanks & Regards, Anil
