Each user can individually suppress this message by going to the Manage UI Preferences page and set the "Message Notification View Time" time to 'Notification Off'.
You cannot, however, do this on a system wide basis. You may be able to customize Workspace to not display this message but even at that level you would be suppressing all messages and not just this one.
Hey Robert Thank U,
you are right..
we can achive this by customizing the Approval Container in workspace..
Hi Chalukya, Do you have any thoughts on what kind of customization in the Approval Container of workspace gets rid of this message?
