The SuiteCRM Reporting module is pretty good at what it does, however there are a few things that it doesn’t allow you to easily do. For example, say you hold regular events, you have added all your delegates and want to see how many events each of your contacts attended last year. Due to the way the Attendance information is stored you can’t currently filter only contacts marked as attended in the reporter.
Once installed the module provides a free text box that allows you to add manually crafted SQL to your report. This allows you to further filter by the fields that AOR Reports does not currently allow you to (for example the Events Invite/Acceptance status).
Additionally the module provides an Analysis mode for the AOR Reports editor, allowing you to view the SQL that will be run. All SQL is cleanly formatted for ease of review.
