Problem List Columns
You can select the columns you want to view in the problem list. You can change the display order of a column and specify how you want to view the contents of a column. You can pin columns so that their position is static. A pinned column appears in the position you assign in the View Preferences window. Each column heading also has an up arrow and down arrow
to control whether the column content lists in ascending or descending order respectively. For example, if the Onset Date column heading displays a down arrow, the problems with the most recent onset date appear at the top of the column and the problems with the oldest onset date appear at the bottom of the column. The up arrow would reverse this display.
