Unable to find OAF DFF attribute's to personalize.
I am having an issue finding the individual DFF’s that appear on the OAF customer standard page and are defined under Receivables/Address Information Descriptive Flexfield Segments form. I cannot seem to find them under the personalize content as I would like to personalize them. Just wondering if someone could assist me on why I do not see them or what I need to do to view them. The DFF's circled are the ones I am interested in although there are others also on the page. Currently running EBS 12.1.3. Thanks.
