Tasks which are run from the GUI can generate various error messages, warnings and information messages. These messages are written to the SAS log and may also pop up a dialog to alert the user.
Warning dialogs include a check-box, which allows subsequent occurrences of the same warning to be ignored, so that no further user interaction is needed. However, all occurrences are still written to the log. The warning is re-enabled next time the task is run.
