Find user that added object to application

For most design objects you can use the "Versions" functionality available in the dropdown in the /design interface for that object. For design objects that don't maintain a version history, you could probably infer that information from the changes to the Object Rolemap log as per: docs.appian.com/.../Logging.html

I guess there is no way that they will come to know that who has added the objects to the application unless you modified or created them. Don't worry.

you can check for recent activity, if someone modified some objects or added some objects would be reflected on the top of the application.

Agree with Venkat. If objects are added to Application it will just show the names of user who last modified or created it.

Unfortunately, versions and last modified dates aren't useful in my situation. The objects in question were last modified about a week before they were added to the app, and the users that modified the objects have told me that they didn't add them. Thanks for everyone's help, but I think I'm finding that the answer is that there is no record of the actual user that adds an object to an application.
