When you are in the SAS Life Science Analytics Framework 5.4.1 Data viewer and you attempt to change the order of a column that appears in the data set, you are no longer able to position the column to a location in the data set that is not currently visible.

Note: The reported behavior represents a regression. In previous versions of the application, you could drag the column left or right to any position within the data set regardless of whether the position was currently visible. 

A fix for this issue is being considered for a future software release.
