Replace FM 'WS_DOWNLOAD' with THE FM 'GUI_DOWNLOAD'

Hi,

I want to replace the obselete function 'WS_DOWNLOAD' with THE FM 'GUI_DOWNLOAD'

cause of unicode .

But I have a problem if the table in the function include data element type datum (8)

and the value is empty there are no 8 blanks charcters in the file,

but in the obselete function module 'WS_DOWNLOAD' there are 8 blanks charcters

How can i solve the issue?
