How can I add a manager as a filter attribute on the Manage Certification Report screen.

Any searchable identity attribute becomes a filter attribute. You cannot filter on the existing manager attribute. The best approach would be to an extended attribute, make it searchable and populate it with the manager value. The document attached to the case outlines the steps to do the same.

Addition of the "Manager" in the filter Solution:

 In order to populate manager as a filter attribute on Manage Certification Report screen, we need to add the manger attribute value in Identity Mappings.
