The Dispatch Chart Job Cell Selections is used to select what job and operation fields you want to appear in the Dispatch Chart's grid job cells.  Since there is not a lot of room to display information in each job cell, it is suggested that you limit the selection of columns to only "must see" columns.

To access Dispatch Chart Job Cell Selections, select View | Job Cell Selections from the Dispatch Chart.  The following window will appear with two tabs; Job Column Selections and Operation Column Selections.
