Ran into a quirk with the report map.
I have a couple instances of "select 'dbr.report'" commented out in SQL (using "--") in various reports and they were being shown as "connected" in the report map. I tried switching to the other commenting style (/* */) and it still left the reports connected as well.
Only once I completely remove the code does it remove the connection on the report map.
Don't know if this is by design, but thought, at least, I'd report it. In a way it was nice because it caught my attention that the 2 reports were connected... but it ends up kind of being a "false positive" though.
Thanks,
