Within Element Reduction, the Trial Balance was not displaying all of field elements. To recreate:
Launch IWS Select
Open XPanels
Select the Element Reduction tab
Select the Trial Balance Object
The fields on the screen with display with a large majority of the date fields not exposed.
These elements are not displayed because these are calculated value from a few DB fields and can't use in a profile. To address this issue, the logic was improved for displaying the calculated elements in the XPanels (not available for save to a profile).
