Can anybody please advise what happens to the migrated standard default permission sets i.e. FND_ENDUSER, FND_DEVELOPER, DOCUMENT_ATTACHMENT_VIEWER etc.,

Do they get updated or replaced?

Also, what would happen to the standard default permission sets if a customer had made amendments to one of them, instead of copying and amending?  Would there changes be overwritten/removed.

The reason for asking is because some REVOKES have ‘disappeared’ after the deployment, when, they were there just before going through the deployment step.

Thank you for your help.

John
