Hello Vince,
What I understand is that running in report mode basically is a 'trial-run'.
It will perform all actions needed, but will not execute them. The provisioning report will be created, so you have a way to examine/resolve any errors before actually running in normal mode.
As long a syou keep the tick, the actual execution (updating the database and stuff) will not happen.
Ours (*as you understand) does not have report mode, except after a first run after an upgrade.
Regards,
Gertjan
