Hello @Thennarasu,
This subject has already been addressed by @Jean-Marc in Date of creation of a Revit element but anyway, here’s an application that shows more or less how it can be applied: Implementing the TrackChangesCloud External Event.
The way I tackled it was by saving a “print screen” of data on a sheet in an Excel file as suggested in the References by @jeremytammik:
- Data (central point and certain parameters) of model elements of interest
- Save the name of the sheet with the user name at the moment “-” date
After that, I would be comparing two different saves. It’s a lot easier than using hooks or another sort of complex method which at the moment I’m a complete noob 
.
I hope it helps you
