I am downloading a table from SAP into a excel using gui_download using the FM in following way
call method cl_gui_frontend_services=>gui_download
filename = 'C:/test.xls'
write_field_separator = 'X'
data_tab = iexcel.
Where iexcel contains all the SAP table contents
This is working absolutely fine . Later on I am modifying the the downloaded file and trying to upload using the FM
Now the problem is
CONVERSION_FAILED = 1 "
So I am getting conversion failed error.
What is the problem in this approach .. and is gui_download giving me .xls only ???
