If you need to view detailed information about two profiles to determine whether they should be unresolved, view them on the Duplicate Records comparison screen.
Display a set of potential duplicates on the Duplicate Records comparison page, as described in Finding Potential Duplicate Profiles on the MIDM.
Beneath the duplicate profile you want to mark as a potential duplicate with the Main EUID (the profile in the far left column), click Potential Duplicate.
On the confirmation dialog box, click OK.
The status of the potential duplicate entry is changed from Resolved and the profiles are once again regarded as possible duplicates of one another.
