@Jenny Franklin - in regards to the new Datalink, I can confirm that enabling check in for a connector only works on the table that is the target.
Example scenario:
Connector 1 -> Table A (check in disabled)
Connector 2 -> Table B (check in enabled)
Only Table B gets checked in, regardless of the ordering of the connector jobs. It's a tad annoying as we have multiple connectors running daily so a multitude of check ins occur overnight. They are all "daisy-chained" (great functionality), so one job completes before the next commences. Thankfully our stage calc times are under 3 hours so I typically find when I start the day the last build is pretty much winding up.
Not sure on groups here - I was not able to use this functionality due to limitations with other aspects of the new Datalink and workarounds I had to come up with to manage these.
