BSY957E New configuration makes column size invalid.

Explanation The requested column sizes make at least one unfixed
column undisplayable. The cursor is positioned on the value where
the problem was detected. The unfixed area on the screen would be
too small to show the column where the cursor is placed. 

User response
 Do one of the following: 
Make the column where the cursor is smaller so that it can fit
in the available unfixed area

Set it to its maximum size (width)

Make the fixed area smaller
