When users have logged a request through the service manager 2012 portal and they go back in to add user input they sometimes receive a message that says " The update operation is not allowed in the current state of the request." The state of the request has not changed it is still Active and has not breached its service level .
I can't seem to find any information about this error and don't know how to troubleshoot it. Any help and advice would be appreciated.
Thanks
Sarah
