The Data Report session type can be used to empower any/all users to generate reports, without having to grant them access to the actual server.
Create a Data Report entry and define the connection string by either:
Specify the connection in the entry itself.
Use a credential entry.
Inherited from a parent.
Prompt for credentials.
Specify the parameters by setting the name, type and default value of all parameters.
Enter the query in the Query tab, which features an SQL syntax-highlighted text box with line numbers.
Ensure that your DBA sets the proper user groups, and that each specific user(s) has access to it.
