Is there an audit log capability I can enable such that I could generate a report or look at a central log file that shows who changed what object and field and value from original to new within the last six months?
I don't know if this would help but there is a changeItemData public object you can use to audit and create a report based on that.
Select [ChangeItemDataPublic] Where [Creation Date] > "1/1/2018 2:00 pm"
You could also enable the "repository Activity" tab in the thick client (Under the Navigation menu) and look at changes made on any given day. There is also an option under the "File" dropdown menu of the thick client (called "Properties") that allows you to select a "range" of transactions where you could see all changes made (the sub tab where you will find this is called "Update").
This may not be exactly what you are looking for but I thought you might still find it useful. Also, if you haven't already, you can look through our online documentation under the "Administration" section to see what that may turn up
Hope that helped.
