How do you revert personalization’s back to seeded to see additional functionality/options that was

Hello All.

 

We are currently running R12 and are upgrading to RUP 6, we would like to revert personalization’s back to seeded to see additional functionality/options that was hidden/removed without using the profile Disable Self-Service Personal set to yes? Is this possible?

The one problem that we are facing is that if the profile Disable Self-Service Personal is set to yes, we firstly get the warning that personalization’s are disabled, and a lot of the pages do not display (as an example, there are additional fields displayed on the leave pages so we can see what is hidden, but the 'submit new leave' does not work.), so we need to add some personalization’s back to get the functionality to work.
