prompt issue in report studio

[rashmi.cognos]

Hi,
Some of the users who create their report are getting issue suddenly in report studio with prompts. When they try to validate a query by generating tabular data or try to generate SQL for a query, they get prompts but after applying values in the prompts, they get permission denied error while submitting. They do have report author access. I as an admin do not get this error. Users are getting in all reports. browser is IE8. Cognos version is 8.4.

Details of the error is in attachment. Any guidance is appreciated as this is a production server issue.

Was anything changed/updated on the server like javascript or any other application? Have you checked the browser compatibility?

No, I checked many files in prompting folder...webcontent\prompting...
dates of the file seem to be very old...dated back to 2009

cognostechie, thankyou for the response

where  and which files should I check on the servers...

[cognostechie]

Rashmi - It seems to be denying access to the javascript files in that folder which is shown in the error message. Can you check the permissions of that folder on your Cognos app server ? Files dating to 2009 may be ok because that may be the last time that file was modified. Those are source code files. These kind of things usually happen after an upgrade of something.

Thanks Cognostechie. What kind of permission should I check for? I think, if it is at application server, permissions should already be restricted to admins?
