Little tip: If the standard hierarchy is maintained in Production, then you must sync it together with the master data back to QAS and DEV systems. Otherwise authorizations don't work the same, additionally because the master data is different.
But as you are posting with an anonymous user claiming that SAP told you to do something rather strange, you must open a customer message with SAP using your own real S-account. They will help you further or also update this thread..
Cheers,
