ALM 15.5.1 - Audits for Test Case Folder Deletion

Hi Team,

One of my users deleted a folder from Test Plan.

I can see the test which were under the Folder are visible under the Unassigned Folder. 

I searched through the Audit Logs but couldn't find any which might be related.

My Questions:- 

  • Are there any audits which we can use to identify which user deleted the folder?
  • If i create a new schema from DB Backups, which tables should i be checking.
    Just TEST and ALL_LISTS or any others?
