PER_ACT_REASON_USG_DFF

Hello

We have created a Descriptive Flexfield on the PER_ACT_REASON_USG_DFF but can't find them

We cannot seem to locate where in the application it should display. 

We would expect it to show on either or both of the Manage Action or Manage Action Reason screens, but they are not there.

Any idea where it can be reflected ?

Thanks
