Good morning everyone,
we're currently performing a system update using SUM and encountered an error during downtime phase.
This error makes it necessary to implement an SAP Note. The SAP Note requires a Message Class to be changed (SE91) manually.
Now the problem is that the system is locked during update so the only Users I am aware of that are allowed to logon to the system are DDIC and SAP*
Sadly neither of them is allowed to change Message Classes within a Customer System. :-(
Any idea how I can solve this problem without having to restore the system and start the update from the beginning ?
Regards,
Thomas
