Can you please explain the use case in detail
Example: If person A made changes in MDM and Person B doesn't know what changes he made Person A and we need to extract report what change's happened in recently in MDM and IDD.
Based on the KB We can track Logging information and which user was logged in last and we cannot figure out what are the change's he made user Hub level or IDD level.
If you're looking for configuration level changes like changing an object in hub console, you could try using below SQLs which will have the change list summary
select * from c_repos_met_change_exec order by create_Date desc ;
select * from c_repos_met_change_exec_item order by create_Date desc;
