The columns displayed in a Trace View can be customized similar to List Views. Each Trace View level is customized individually. Like List Views, you can customize what to display in Trace Views. Each level has options to turn on field data you want to see.
Select Add Columns in any level to turn available fields on or off for that level.
Select a column to add it to the view. To remove a column, select it again. Selected columns will have a checked box.
If there are multiple item types in a level, options to sort the fields appear on the left side of the panel.
