Secured List View in PER_PERSON_HISTORY_ASSIGNMENTS_UE

Content

We have a Fast Formula which is built a year back and uses a DBI form PER_PERSON_HISTORY_ASSIGNMENTS_UE . Is Oracle changed the query behind this UE? because I see a secured list view(PER_ASSIGNMENT_SECURED_LIST_V) in query behind that UE. As per my understand UEs with PER%SEC% will have the secure list view. Because of this, the Fast Formula not working properly when we log in as an employee. But it works fine when we login as implementation user.

Can anyone tell me Do I need to raise SR? or is Oracle's query behind this UE is correct and I need to change the Fast Formula with alternate DBI?
