How do I determine what tasks a user has prior to transferring?

We have an automated user integration that runs daily.

There are some users that get the following error when the integration attempts to delete their access: "The user you are trying to delete owns at least one requisition, task, folder, meeting or is associated to a department. Before deleting the user, you must first transfer his work items to another user.;"

We know how to transfer tasks to another user - however, we'd like to understand what it is we're transferring over to the new user.

Are there any suggestions or recommendations?

Thanks.😊
