No doubt this is discussed somewhere here but I've only found tangential topics so far.
It would be extremely useful to have a list of report sources for creating custom reports - ie what tables and fields (columns) are included in the sources and how (if at all) one could add new sources directly the database - all I see is a message saying I can't configure this through the admin interface.
At the moment I can only view the components of sources by tedious trawling through the sources one by one.
There is a third-party block for Moodle called Configurable Reports - this would be a useful addition to Totara.
Thanks
