Hi:
When I try your code in SAS 9.2, with AUTOFIT, I see that Excel has just widened the table instead of wrapping the text. So, my long text was taken care of by the cell -width- being increased by Excel but I -do- see all the text in all the headers.
In the SAS Log, when I use the Doc='Help' suboption, it says this about the AUTOFIT_HEIGHT suboption:
[pre]
Autofit_height: Default Value 'no'
Values: yes, no, on, off.
If yes no row heights will be specified. This allows the auto fit height
of Excel to do it's job, sometimes not so well.
[/pre]
It seems that you are experiencing the "sometimes not so well" behavior. Perhaps Tech Support will know what combination of sub-options will cause the cell height in Excel to increase (and the text to wrap) as you want.
