Question : SQL Reporting issue

Having an issue where users cannot access the reports thru their pc browser, I can access them directly on the server.  When they go to the url and try and open/run a report, this message appears:

An error has occurred during report processing.
Query execution failed for data set 'Application'.
For more information about this error navigate to the report server on the local server machine, or enable remote errors

They do have access, for some reason its not allowing for access to the reports from the client machines.

Answer : SQL Reporting issue

looks like the users dont have access to the underlying sql tables.
please verify that users have access to the reports.
datasource is using the correct security context.
