I am new to the DRM tool and was trying to get the above trackings to be in DRM, I did as mentioned, but the information is not populating in the properties for created user,created date, I have enabled the track changes and also assigned the created user with addedby,addedon property in the system preferences ..please let me know if i need to do any thing more to populate these propeties with the information.

[...] enabled TrackChanges System preference – Created a property called NodeChangedFlag (You mention in your article that I can pick and choose the preferences I want to use. So I leave out the rest) – Updated the [...]

Here are the error messages I see…

So after I tried setting all of the above properties/ system preferences, I am able to change all except one preference (ChangedOnProperty) without any issue. It looked like the system preference was expecting a boolean user property instead of a string. So I changed the user property UpdatedOnDate to boolean (even though it doesnt make sense) and I was able to point the sys preference (ChangedOnProperty) to UpdatedOnDate.

After this setting, the DRM Engine refused to restart. I did not capture the error but the logical assumption was incorredt the system preference (ChangedOnProperty) setting.

My question is that
1. why would DRM not allow ChangeTracking for a select range of system preferences, or did I do something wrong
2. Is there a known issue with the system preference ChangedOnProperty or again did I do something wrong.

I guess I really would want an solution to my problem, where I am trying to highlight the Nodes that were changed in DRM after a certain date & time in some way (Change in Font style, glyphs, etc)

BTW, to get the system up and running, I had to update the DRM database table and empty out the values.
