Descriptions not proper on F4 help

Question

Hi All,
I have a header variable for which on F4 help the descriptions are getting truncated. While after selection and exectuion of layout you can see the full description.
Tried debugging the F4 functionality but there it seems to populate values of text correctly. All text are maintained at medium desc.
Also the decsription / text is in Chinese language. Could this be the problem?
Any help would be appreciated.
Thanks !!!
Vidya.

Implement the following code.  This should give you some hints.  FYI, in this sample, you will only ever get one value in the dropdown box.  You can only have one creation date for a sales document header.  I was assuming that you were using as example.
