My first reaction would be to suggest to redo the same by hand in your PROD environment ...
These permissions are saved in the web catalog in the system folder ("privs" subfolder if I'm not wrong), so you can also probably move them around environments by moving the catalog itself.
Christian Berg any other idea?
Have a look at Manage Presentation Services Privileges in OBI 11g , the question is for something else but the answer is interesting for you.
Note 1537592.1 provide some info on where the privileges are stored.
thanks Gianni.. It worked for me. :-)
