The Indicators field displays a small icon that represents information for a task or resource. The Indicator field is located (default) to the right of the ID field and appears in a number of tables, given the number of different types of information about a task or resource i.e. a completed indicator either alerts or communicates to the project manager that the task is completed, and a note indicator means that a task or resource Note is attached.
Unlike other fields, the Indicators field is represented in the title line by an icon instead of a word, such as the Task Name field.
Add the Indicators field to a task view when you want to display the indicators that give quick, graphical information about tasks.By default, the Indicators field is the first column in the Gantt Chart view and Task Sheet view. When you point to an indicator in the Indicators field, a ScreenTip provides more information.
