Is there a database scheme available for v11.4?
Is there a custom reports library available in the community?
There are some custom reports consultants available for hire. Their info is out here on the community here - Track-It! Reporting & Consulting Services
There is also a database diagram in the docs for 11.4 here - Home - Track-It! 11.4 - BMC Documentation
You can always click Help inside Track-It! or go to http://docs.bmc.com and search for the version of the product you need docs for.
I believe the Hours are also on each note in this new version and then totaled up into a field on the screen. You may have to total the note hours in the report.
