I'm in trouble,thanks for all your help!
our data is stored with simple chinese,when we download ABAP EXCEL report in simple chinese
OS ,It's OK,
but if we use Traditional Chinese OS(some boss used) to download,we can't get the char right,
we use GUI_DOWNLOAD FUNCTION,and I've tried code page "8300" to instead "8400",
the filetype = 'DBF'
our basis don't agree to set up Traditional Chinese language package,
