Within Windchill, I've been trying to sort a column full of dates to show the most recent ones to the oldest ones. For unknown reasons, the dates are not sorting correctly. It seems whenever I sort the column, the dates just get randomly mixed up. (See attached for example)
I am confused. The image you attached is a sorted list. It looks proper and not mixed up. I have seen sometimes you need to ungroup things first to get a proper sort.
Another question would be did you wait for the table to fully populate on the page? If you sort or group before the table is fully populated, you will get mixed results.
