Dear Ali,
The reported solution is only valid after SAP Support intervention, as they need to cancel SPAM import queue (currently locked in your system).
The SAP Note implementation is only valid after SAP intervention to release the queue, manual SAP Note implementation doesn't take effect while SPAM queue is locked.
SAP will request you to confirm for a valid backup of your environment and then, they will release the SPAM queue.
Only after that, you'll be able to implement both SAP notes and your SPAM upgrade will work successfully.
Please get in contact if additional information is needed.
Best Regards,
Herman Arancibia
