The Job Gantt Chart Grid Selections is used to select what job and operation fields you want to appear in the Job Gantt Chart tree.  Since there is not a lot of room to display information (the screen is typically taken up by the cart itself) it is suggested that limit the selection of columns to only "must see" columns.

To access Job Gantt Chart Grid Selections, select View | Column Selections from the Job Gantt Chart.  The following window will appear with two tabs; on the Job Column Selections you select job columns to display and on the Operation Column Selections you select the operation columns to display.  Note that the job columns are always displayed on the job row and the operation columns are displayed on the operation row.

Operation Column Selections

The following columns can be displayed on the operation row of the tree in the Gantt chart.
